The suspect in a gun attack on the Champs-Élysées that left a policeman dead was long known to the police but had shown "no sign" of radicalisation, Paris Prosecutor François Molins said on Friday

"Karim C. had previously served nearly 14 years in prison on three counts of attempted murder, including of police officers, as well as for lesser offences."

So despite sky news still reeling out terrorism 'experts' talking about 'Islamic terrorist' attacks

its just another nutter who hates cops.
