What we know about Champs-Elysees gunman as Paris home raided
"I never noticed anything abnormal about the guy," a neighbour says of the man whose Paris family home is searched by officers.
The man police believe carried out the shooting on the Champs-Elysees in Paris had reportedly been flagged as an extremist to French authorities.
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.
The Frenchman was convicted of attacking a police officer in 2001, according to archive reports in the French newspaper Le Parisien.
Cheurfi was also known to have extreme beliefs, according to two police officials, speaking to AP on condition of anonymity because they were not authorised to publicly talk about the probe.
A 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.
Police tape surrounded the quiet, middle-class neighbourhood as residents expressed their dismay at the searches.

The gunman was shot dead at the scene and a pump-action shotgun and knives found in his car.
An anti-terror investigation is under way into the incident at the heart of the French capital, which Islamic State has said it carried out.
The extremist group named the attacker as Abu Yusuf al Beljiki and suggested he was a Belgian.
Interior ministry spokesman Pierre-Henry Brandet said it was too early to say what the motive for the attack was, but that it was clear the police officers had been deliberately targeted.
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.
