French investigators said Thursday that the police officers in Paris who sodomized a young black man with a baton did so accidentally, and that the incident does not constitute rape.

The 22-year-old youth worker, identified only as Théo, says a group of four police officers physically and sexually assaulted him on Feb. 2. He says he confronted the officers after seeing one of them slap a young person during an identity check. Then, Théo says, the officers took him around the corner and sodomized him with a truncheon, spit on him, beat his genitals and called him names, including “negro” and “bitch.”

Théo suffered severe anal and facial injuries during the incident, parts of which were captured on video. He was immediately taken to the hospital for an emergency surgery. French Interior Minister Bruno Le Roux announced Sunday that each of the four officers has been charged with aggravated assault, and one was charged with rape.

Police have claimed Théo’s pants “slipped down on their own” and his wounds were sustained accidentally, according to French media reports. An early investigation by France’s national police force concluded that the incident, while “very serious,” was “not a rape” due to the “unintentional character” of the officers’ actions.

Video shows an officer “applying a truncheon blow horizontally across [Théo’s] buttocks,” a police source told The Local. While investigators acknowledge that Théo was penetrated, they say it was unintended.
