By BI: Grenoble attacker, Yassin Salhi, the French MUSLIM who allegedly decapitated his boss and hung the head from a company fence took a selfie with the severed head — and shared the perverse pic with a friend.

NY DAILY NEWS  Yassin Salhi, 35, allegedly sent the gruesome photo via WhatsApp to a Canadian cell phone number, according to officials. French investigators were hunting for the recipient of the selfie, but were unable to confirm media reports that it was a person now in Syria.

Salhi was arrested Friday after killing his boss, Herve Cornara, and unsuccessfully trying to set off an explosion at the U.S.-owned Air Products factory near Lyon by plowing a truck into an area containing flammable liquids. The suspect instead caused only a small explosion and was attempting to ignite bottles of acetone when he was overpowered by firefighters.

Before his capture, Salhi allegedly strangled and beheaded his boss, took the perverse photo, covered Cornara’s head in Arabic writing and attached it to the gates of the factory along with homemade ISIS flags, officials said. “This macabre act of decapitation, staged with flags, is new in France.”

In a scene echoing the gruesome violence used by Islamic terrorist groups in Syria, Mr. Salhi’s 54-year-old boss was found decapitated, prosecutors said. His head was affixed to a fence and framed by a pair of flags emblazoned with the shahada, an Islamic creed declaring “There is no god but God, and Muhammad is the messenger of God.”

Salhi, who does have a history of radical ties, remained in police custody Saturday in Lyon along with his sister and wife. The father of three initially refused to cooperate with French authorities.

Not sure if this is the same person, but According to the JTA, a man called Yassin Salhi was given a six-month suspended jail sentence in 2012 for attacking a Jewish train passenger travelling from Paris to Lyon.

The assailant, who was not identified by name in French media, hit a man wearing a kipah on Jan. 26, 2011 aboard a train traveling from Paris to Lyon. “You Jews with your skullcaps, you think you run the world,” he said, adding profanities. The assailant then followed the Jewish man to the train bar, making derogatory remarks about him, his mother, father “and your whole race.” He then hit the man in the chest.
