French media is reporting the gunman who shot dead a policeman in Paris on Thursday was the subject of an anti-terror probe which had marked him as a potential Islamist radical.
The incident took place on the Champs-Elysees in the city's 8th arrondissement last night. After pulling up beside a police bus, a 39-year-old man got out and opened fire on the police with an automatic weapon, killing one and injuring two.
He was later shot dead in a confrontation with security forces. The incident saw the whole of the Champs-Elysees evacuated, while authories took control of the situation.
The gunman has now been named as Karim Cheurfi. Parisian media is reporting he was a local to the city and lived in its suburbs, while Islamic State - which has claimed responsibility - originally named him as Abu-Yusuf al-Baljiki.
Local media also says he served several years in prison for attacking police officers with a gun in 2001.
President Francois Hollande is to chair an emergency cabinet meeting on security to deal with the issue as the country goes to the polls for its next presidential election on Sunday.
