The perpetrators carried out thefts of detonators and explosives from Luxembourgish quarries. The perpetrators used the stolen materials to blow up electricity pylons from the electricity company
Cegedel. The company received multiple ransom letters. The company contacted the police and decided not to pay. Later, once the company had come to a conclusion and decided to pay the ransom, the perpetrators declined the transfer of money, stating that they knew of the police interest surrounding the attacks. Cegedel's electricity pylons remained the target of later attacks. However, the perpetrators diversified the targets of their later attacks to include the headquarters of the
Gendarmerie and the Palace of Justice. A particularly significant incident happened during a meeting of the
European Council on the
Kirchberg plateau. The incident in question involved a small explosive device which was thrown out of the window of a moving car. After two further attacks, one a car bomb at the apartment of a
notary, and the apartment of a retired commander of the Gendarmerie, the attacks ceased. No-one was killed in the 18 attacks. However, a young soldier was killed during service by a traffic collision during the surveillance of
Luxembourg Airport. The perpetrators also set up an explosive trap in a forest, which was discovered before it could be put to use. This could perhaps have resulted in the death of many people. Furthermore, an engineer’s hand was severely injured when he picked up a flashlight which had been fitted with a detonator. A number of people were injured as a compromised electricity pylon fell upon a highway, which caused traffic to collide on the highway, though nobody was severely injured. It is believed that the perpetrators wanted to avoid human casualties, though in a number of incidents it was pure chance that no-one was injured. ==Chronology of the attacks ==
