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.

A firefighter seized the main suspect following the France terror attack in which a businessman was decapitated. The suspect, Yassine Salhi, was flagged in 2006 for suspected ties to radical Salafists, France's Interior minister Bernard Cazeneuve said.
Mr Cazeneuve said Salhi - a resident of the Lyon suburb of Saint-Priest who is in his 30s - had been known to intelligence services and was under surveillance from 2006 to 2008.
Officials said the decapitated man was the boss of a local transportation company that employed Salhi. One official said he was believed to have been killed before the attack on the factory and was not killed by the explosion.
