On 9 May 1970, at 10:30 pm, the place du Huit-Septembre (September 8 Square) is shaken by an explosion. The Besançon courthouse was just attacked with a bomb containing explosives and scrap metal. Damage is impressive but limited : only the porch, the bay windows, and the salle des pas perdus (hall of lost steps), partly classifieds, are seriously affected. A couple and their baby narrowly escaped of the impact, but no one injuries are deplored. The mayor, the socialist Jean Minjoz, immediately condemns this act, while the investigation begins. Witnesses say they saw a man throw a device through, before escaping in a car's of an accomplice. At first the attack was attributed to the left but two individuals were finally arrested on 14 May with the number of their a registration plate. They was former soldiers, workers at the Rhodiaceta factory, one was a member of the OAS and the other a member of the UDR acting for defiant motives possibly related to power through the SAC. The suspects admit the facts, while weapons and ammunition are found. See also
