A delivery man who beheaded his boss and rammed his car into a pile of gas container at a US-owned gas factory in southeast France was detained minutes after he tried to open canisters containing flammable chemicals, prosecutors said on Friday.
The attacker, his wife, sister and a third person were taken into custody for questioning after he was caught injured in the blast on the industrial zone near the town of Saint-Quentin Fallavier to the south of the city of Lyon.
French Interior Minister Bernard Cazeneuve identified the suspect as Yassin Salhi.
“This person was under investigation for radicalisation but this investigation was not renewed in 2008. He had no police record,” he added.
Sahli was a 35-year-old professional diver from the Lyon suburbs, said sources close to the investigation.
The assailant beheaded his boss, 54-year-old victim, before trying to blow up the factory. Two people were also injured in the attack.
The head of the victim was discovered dangling on the factory’s wire fence framed by two flags resembling ISIS when the police found him, said Paris public prosecutor Francois Molins in a news conference.
The attack occurred on the same day that a gunman killed at least 37 people at a Tunisian beach resort as ISIS suicide bomber killed 25 at a Shia mosque in Kuwait.
“It is a terror attack. There is no doubt about it,” French President Francois Hollande told reporters in Brussels before leaving a European summit to return Paris.
There is no indication that the attacks on three different continents are related or coordinated.
"There should be no doubt as to our country's ability to protect itself and remain vigilant," Hollande added.
No groups have claimed responsibility for the attack and the reason of the attack still remains unclear.
