A man believed to have been an accomplice of the shooter who killed a policeman on Paris's Champs-Élysées in April has been placed under formal investigation and remanded in custody, a French judicial source said on Saturday.
The man's DNA was found on the weapon used by the gunman, identified as Karim Cheurfi, who opened fire on a police vehicle parked on the famous avenue, killing one officer and injuring two others before being shot dead.
The man was unknown to anti-terrorist services, the source said.
