French Interior Minister Bernard Cazeneuve says multiple people are in custody after an attack on a gas factory that left one person dead.

A severed head was posted at the factory’s entrance and Cazeneuve said authorities are still trying to identify the victim.

“People who could have participated in this abject crime are in custody after having been arrested,” he told journalists.

The attack began when a car crashed the gate and plowed into gas canisters, touching off an explosion at the factory near Lyon on Friday morning.

Cazeneuve said the suspect was believed to be from the area and had been flagged in 2006 for ties to Islamic extremists, but surveillance was dropped in 2008.
