The gunman who shot dead a policeman on the Champs Elysees in Paris in an apparent Isil-inspired terror attack before being killed has been named as French national Karim Cheurfi.

The group's president, Mickael Bucheron, told The Associated Press the slain officer would have celebrated his 38th birthday at the beginning of May.

Jugele was among the officers who responded to the gun and bomb attack on Paris' Bataclan concert hall in November 2015, part of a wave of assaults in the French capital that killed 130 people, he told People.com when the venue reopened a year later with a concert by Sting.

People quoted him as saying how happy he was to be at the "symbolic" reopening, "here to defend our civic values."

"This concert's to celebrate life. To say 'No' to terrorists," it quoted Jugele as saying.

Authorities earlier revealed Cheurfi - who was jailed for 20 years for trying to kill officers in 2001 - had been under preliminary investigation for terrorism and was detained two months ago but “let go”.

His victim has been identified as Xavier Jugele by Flag!, a French association of LGBT police officers.
