Police believe planning for the bombings was led by
Noordin Mohammad Top, who also involved in the
2005 Palu market bombing. The first meeting had been held on 30 April. Ibrohim, a florist who worked for a florist company which had stores in both the bombed hotels, was another key organiser. Ibrohim was recruited in 2000 by
Saifudin Jaelani, his brother-in-law, while he was working as a florist at the Hotel Mulia in Jakarta. In 2005, Ibrohim and Jaelani were inaugurated as members of Noordin's special forces. Ibrohim set strategies, conducted surveys of the locations and smuggled the bombs into the hotels. Saifudin Jaelani is believed to have also recruited the suicide bombers for the operation. The bombs were smuggled into the JW Marriott one day before the blast through the hotel's loading dock using a pick-up truck rented by Ibrohim. The bomb design and materials of an unexploded bomb found by Police in room 1808 were identical to those used by Jemaah Islamiyah in previous attacks. The suicide bomber of the JW Marriott Hotel was Dani Dwi Permana, an 18-year-old graduate of a private senior high school in
Bogor,
West Java. The suicide bomber of the Ritz-Carlton hotel was Nana Ikhwan Maulana, a 28-year-old former resident of
Pandeglang,
Banten. Dani rented room 1808 in the JW Marriott. The room was paid for by Amir Abdillah, who was arrested on 5 August. On 7 August, police raided a house in
Temanggung,
Central Java. Three people were arrested and one person was killed, later identified to be Ibrohim. On 8 August, police raided a house in
Bekasi,
West Java, killing two people believed to be preparing to attack the Indonesian president
Susilo Bambang Yudhoyono with a truck bomb near his private residence in
Bogor,
West Java. Funding for the bombings is believed to have been provided from the Middle East. A number of suspects, including a Saudi Arabian national, have been arrested by Indonesian police for their involvement in handling the funds. == Aftermath ==
