The main suspect in the beheading of a businessman took a "selfie" with the slain victim and sent the image to a Canadian mobile phone number, officials said.
French investigators were working to determine the recipient's identity, but were not able to confirm reports that it was an unspecified person now in Syria, where the radical Islamic State group has seized territory.
The main suspect Yassine Salhi, a truck driver with a history of radical Islamic ties, as well as his sister and wife remained in police custody in the city of Lyon, a day after he allegedly crashed a truck into a US-owned chemical warehouse and hung his employer's severed head on a factory gate, officials said.
One of the officials said the selfie was forwarded via WhatsApp to a phone number in Canada.
