Yassine Salhi, suspected of carrying out an attack at a French industrial gas factory on Friday, was also allegedly involved in an anti-Semitic attack in 2012.
Salhi, 35, a married father of three, is known to have ties to Salafist radicals in France, and was under surveillance from 2006 to 2008.
Three years ago, Salhi and another man allegedly hit a Jewish teenager and Salhi allegedly hurled anti-Semitic abuse at him while they were traveling on a train from Toulouse to Lyon.
A French prosecutor said Friday there was no sign that Salhi, alleged to have carried out the beheading of his boss and tried to blow up the factory, had an accomplice.
Salhi entered the factory with ease at the wheel of a delivery van which he often drove to the site, where “he was known to employees,” prosecutor Francois Molins told reporters.
On Friday morning, Salhi drove into the Air Products gas and chemicals factory at 9:28 a.m. (7:28 GMT) local time, and disappeared from the vision of security cameras until 9:35 a.m. when the van was seen accelerating towards one of two hangars by one of two cameras.
A minute later a massive blast was heard.
