PARIS, June 11 (Xinhua) -- Three men believed to be involved into Champs-Elysees shooting, in which a police was killed, were put under formal investigation, state-run France info radio reported Sunday.
The three suspects, aged between 25 and 27 years, appeared before anti-terrorism magistrates on Friday and Saturday evening. They were placed under formal investigation on apparent links with Karim Cheurfi who had opened fire on a police vehicle parked in the famous Champs-Elysees avenue in April.
Investigators suspect the men had helped the shooter to acquire the Kalashnikov, an assault rifle, with which he killed a police officer and wounded two others, in exchange for a motorcycle.
A fourth accomplice was indicted in May after his DNA had been found on Cheurfi's rifle.
The Islamic State (IS) claimed responsibility of the attack.
