On April 28, police had tracked Bonnot to a converted garage in the Paris suburb of Choisy-le-Roi. The building had only one entrance so it was easy for Bonnot to keep the police at bay. They besieged the place with 500 armed police officers, soldiers (with one brand new Hotchkiss machine gun), firefighters, military engineers and private gun-owners. By noon, after a sporadic firing from both sides, Paris Police Chief Louis Lépine sent three police officers to put a dynamite charge under the house. The explosion demolished the front of the building. Bonnot was hiding in the middle of a rolled mattress and tried to shoot back until Lépine shot him non-fatally in the head. Afterwards police again had to prevent the spectators from lynching Bonnot. They simply told the crowd that Bonnot was already dead and had been buried in a secret grave. In fact, he was fatally injured but was taken to the Hôtel-Dieu hospital and survived for around another hour.
