Paris (CNN) A man who killed a police officer on the Champs-Elysees Thursday night was known to French security services for radical Islamist activities and had shot and wounded an officer in the past, a source close to the investigation told CNN.
The suspect, who was shot dead by French police, was the subject of a “Fiche S” surveillance file and was on the radar of the French domestic security service DGSI, the source said.
The man was a French national who shot two officers in 2001 after being stopped by a police car, the source said. He was taken into custody but while being questioned grabbed another officer’s gun and shot him three times, the source said. He was convicted in that attack and had a criminal record because of involvement in violent robberies, the source said.
The source said French investigators now believe this was in all likelihood a terrorist attack. They believe there was just one attacker, and the danger is likely over, the source said.
ISIS issued a statement saying an Islamic State “fighter” carried out the attack. The ISIS claim comes via a statement released by the group’s media wing, Amaq. The ISIS statement identified the attacker and called him “the Belgian.” CNN has not confirmed the attacker’s association with Belgium.
Paris Prosecutor Francois Molins said he will reveal the shooter’s identity on Friday at a news conference. He said officers are searching the man’s residence in Chelles, Seine-et-Marne, a Paris suburb, and are trying to determine if he had accomplices.
The shooting has not officially been declared a terrorist act but anti-terrorist forces are leading the investigation, French President Francois Hollande said.
“The people who were present have been evacuated and we are convinced that the leads which point us to this case, and which will allow us to uncover the truth, are of a terrorist nature,” he said.
