A Paris police officer has been detained for possible involvement in the January kosher supermarket attack that left four shoppers dead. French authorities have detained four people for their associations with Amedy Coulibaly, and one is a policewoman who converted to Islam two years ago. She was already suspended from her police duties in February. Her boyfriend was also detained and phone records indicate he was close to Coulibaly just before the Jan. 9 attack. Weekly newspaper Le Canard Enchaine reported that the man may have had access to his girlfriend’s police barracks.
