This is the face of a man whose home has been searched by police in connection with the attack on the Champs-Elysees.

A police document obtained by the Associated Press (AP) identifies the address searched in the eastern Paris suburb of Chelles as the family home of Karim Cheurfi, a 39-year-old with a police record.

He had previously been flagged as an extremist, according to two police officials, speaking to AP on condition of anonymity because they were not authorised to publicly talk about the probe.

Cheurfi’s neighbour said: I think everyone here is in shock. It’s clear that we are in shock. And that we’ve got to this point is very serious. Especially because this doesn’t seem to resemble anyone from Chelles.

I don’t know anyone here who could just lose it and do this kind of thing.

I never noticed anything abnormal about the guy. And this was a guy who was very closed off and was not someone who looked for problems.

Cheurfi was convicted of attacking a police officer in 2001, according to archive reports in the French newspaper Le Parisien.

Two police officials confirmed the main suspect was a 39-year-old from Chelles, a quiet, middle-class neighbourhood.

The details emerged as raids were carried out at a number of properties across the capital and police launched a manhunt for a second suspect believed to be still at large.

It is not certain whether the attack, in which a police officer was shot dead and two seriously injured, is terrorist related but French President Francois Hollande says the Champs-Elysees shooting is terrorist in nature.

An anti-terror investigation is under way into the attack in the heart of the French capital, which Islamic State says it carried out.

The extremist group has named the attacker as Abu Yusuf al Beljiki and suggested he was a Belgian.

Police have issued an arrest warrant for a second suspect who had arrived in the country by train from Belgium.

The French prosecutors’ office said the counter-terrorism office had opened an inquiry.

Interior ministry spokesman Pierre-Henry Brandet said it was too early to say what the motive of the attack was, but that it was clear the police officers had been deliberately targeted. He could not give any details about the suspect’s possible motives and said his identity had not been confirmed.

Security expert Major General Chip Chapman told Sky News: French security agencies know 2,000 dangerous or potentially dangerous terrorists in France. But you only have resources to follow so many.

The incident follows two recent attacks on soldiers providing security at prominent locations around Paris – one at the Louvre museum in February and one at Orly airport in March.
