Government Initial In a televised address to the nation two hours after the incident, Maduro stated that an investigation had been opened immediately and a number of those connected to the attack had been apprehended and charged. Six other suspects were initially arrested within hours of the incident, which later increased to seven. Reportedly, one of these was known to authorities because of his involvement in the
2014 protests, whilst another had an
arrest warrant out for apparently taking part in the
assault on Fort Paramacay. President Maduro also laid blame on extreme right-wing elements in his own country acting together with extreme right-wing elements in neighbouring
Colombia, and specifically named Colombian President
Juan Manuel Santos as being behind the incident. A spokesperson for President Santos promptly denied the accusations. though Minister of Communication
Jorge Rodríguez said that there were three drones used during the incident, Police at the scene had previously said that authorities shot down a drone. Following a brief initial two-day investigation, Reverol presented his findings and explained that the two drones he claimed were involved were loaded with over combined of
C4 plastic explosive, and that one was to be exploded above Maduro's head with the other was intended to explode directly in front of him.
Post-arrests Shortly after midnight
VST on the morning of Tuesday, 7 August, Maduro said that he had "hard evidence" of "the Colombian
oligarchy" planning the assassination, and that he would share it "in the next few hours". Maduro announced in a video at the same time that they now knew that the perpetrators were trained during April and June 2018 in
Chinácota in
Norte de Santander, Colombia, an area which borders the north of Venezuela. In this video he also said that he had been informed that Juan Manuel Santos had told former Spanish Prime Minister
Mariano Rajoy that Maduro would be gone before he left office. The promised report had not surfaced by the afternoon. In the evening, Maduro gave a two-hour
television presentation from
Miraflores Palace which included a partially-censored video of former Venezuelan security official Juan Carlos Monasterios Vanegas, who said he was one of the "bombers", giving a statement blaming
Julio Borges and
Juan Requesens. President Maduro directly accused opposition leaders Borges and Requesens of being behind the incident, also saying that Borges lived in a mansion in Bogotá that the outgoing Colombian government paid for, though no details of his "alleged role" were revealed. In the video, Monasterios claimed Requesens told him "to kill the President". The arrest of Requesens was described as a violation of the
Constitution of Venezuela, specifically Article 200 which states that "only the Supreme Tribunal of Justice, subject to authorization in advance from the National Assembly, shall have the power to order their arrest and prosecution". In response to the accusations, Borges tweeted a statement from Bogotá telling Maduro that he was "not fooling anybody", calling the supposed attack a "farce" that Maduro "staged to justify the persecution of opponents".Maduro's evening presentation claimed that everyone involved in the attack was offered $50 million
USD as well as United States citizenship status. On Wednesday, 8 August, Saab said that investigators had so far connected nineteen people to the attack, and three had already been charged. Maduro also named wanted individuals living in
Colombia and the US state of
Florida, saying he wanted cooperation from these two nations and that he "[trusts] in the good faith of
Donald Trump". Though Borges and Requesens are leaders of the
Justice First party, Reverol revealed that "the majority of the suspects are from the resistance group
Come Venezuela" (sic). Minister of Communication
Jorge Rodríguez gave a national presentation on 10 August announcing that at least one of the drones involved was detonated from the United States, though a report by
The Independent that was warning of drone threats said this could be done "from 5 kilometres" away only, as well as showing a supposed flight map of the drones path from Colombia all the way to Avenida Bolívar. Rodríguez also said that he had submitted a
Red Notice to
Interpol for the capture of "assassin" Julio Borges, and showed a video of Juan Requesens recorded in Helicoide.
Raids and seizures One announcement of alleged perpetrators by Reverol on Thursday, 9 August, included details of several properties that the investigation had seized. They were owned by Delgado, who was accused of helping to finance the attack. Two cars and an apartment in his name were also seized and raided.
Caracas Chronicles reported that the homes of Juan Requesens, Julio Borges and other deputies, Julio Mora and Jorge Mora, had been raided. Rafaela Requesens, Juan's sister and student President of the
Central University of Venezuela, expressed her anger that at least forty SEBIN agents broke into their house, also saying that the government wanted to plant false evidence to incriminate her brother. On 7 August, the SEBIN also raided the house of students Valeria Sosa and Luis Alfredo Sosa, from
Andrés Bello Catholic University and
Simón Bolívar University, respectively, and whose mother is accused of being involved in the drone attack. Roberto Rodríguez, a student leader at Andrés Bello, denounced that the raid was done without a search warrant, that the electricity was cut off from the building, that many belongings in the house were stolen, and that the family were forced to escape.
Requesens videos During his 10 August presentation, Rodríguez showed a video of Requesens allegedly admitting to working with people involved in the supposed attack. In the video, Requesens named several of the suspects, including Borges, though this was limited to him saying that Borges "asked [him] for a favour to help a person get from Venezuela to Colombia". He added that this person was Monasterios and that they had written to Mauricio Jiménez, an immigration official in Colombia, for help with getting passage, who immediately offered it. Requesens gave no details relating to an attack on Maduro. The opposition condemned Rodríguez's actions, saying that Requesens was drugged and tortured into making a false confession. One source from Requesens'
Justice First party assured journalists that the government drugged Requesens to obtain confessions and, when they realised he was still of sound mind, then continued to drug him until he became
incontinent, as well as threatening to murder his parents and rape his sister. In a second video, Requesens is wearing only underwear which is visibly stained with
faeces. Following the release of the videos, Requesens was moved from being held at the prison of SEBIN,
El Helicoide, to the
Palacio de Justicia. After five hours, he was returned to Helicoide with his hearing deferred and being denied to see his lawyer. In a moment of protest and solidarity with Requesens, Venezuelans demonstrated in public while wearing underwear to share moral support for Requesens, who was seen in the government's video wearing underwear covered in faeces. Though he was originally transferred to the court building on 10 August, Requesens' hearing was deferred to Monday, 13 August. This hearing went ahead, lasting two days, and on Tuesday, 14 August he was denied bail. He was remanded in custody after being charged with seven crimes against Maduro and the State, to go on trial and face Venezuela's maximum punishment of 30 years in prison. On 12 August, the government shared a third video of Requesens which it said was part of his confession. In the video Requesens said that he briefly had telephone contact with a man who identified himself as "Alexander", who confirmed that Monasterios had got to Colombia. At his hearing, Requesens told his lawyer, Joel García, that he did not remember recording a confession video or any of the people he named. Requesens also told García that guards gave him the stained underwear to "mock him". None of the videos were submitted as evidence.
Further arrests On 10 August, SEBIN arrested Luis Enrique Martínez Rico, the Coordinator of Security and Defense Commission of the
United Socialist Party of Venezuela (PSUV), the government's political party. Reports stated that Martínez was arrested due to his alleged involvement in the incident. Colonel Garcia Palomo said in a 13 August statement delivered to
La Patilla that "I have no connection with the events that took place in Caracas on 4 August, through the use of drones or the people who they abused, whom I do not know" (sic). On 14 August, the number of suspects had increased to 34, fourteen of whom had been charged, with Saab saying it could rise further. It was also announced that Venezuela were now formally seeking extradition of suspects from
Peru, Cabello accused another deputy of the National Assembly,
Ismael García, of being involved in the "conspiracy" on 15 August. García was a member of
Primero Justicia with Borges and Requesens until he ran for candidacy with
Acción Democrática on 10 August. García had been reportedly attracted the government's attention in the days before this, along with
José Manuel Olivares, who had recently been forced into exile. Maduro said during one speech that he knew that the attackers "were planning a transitional government" and that current politicians were intended to lead it.
Independent One early independent investigation by
NGO Control Ciudadano alternatively claimed that "at least one drone belonged to the military", and that a drone was "shot", blaming the government but indicating that it would be unintentional. Though various bodies and countries asked for an independent investigation to be performed in Venezuela, the practice of
censorship in the nation prevented this from happening. One of the leading independent investigatory organisations in Venezuela,
Armando.Info, was completely blocked in August 2018, with four of its writers also having travel restrictions imposed, barring them from leaving. On 14 March 2019, CNN revealed new details about the plot, based on new videos. ==Responsibility claims==
