Man held after boss beheaded in France

A decapitated body daubed with Arabic writing was left at a US-owned factory in south-east France after an assailant rammed a delivery van into gas containers at the site, triggering an explosion.

A source close to the investigation said the victim was the boss of the suspect, a delivery man.

The two had gone to the company to make a delivery but the assailant killed and beheaded his 50-year-old manager before entering the secured site in the vehicle.
