Four people have been apprehended in relation to the January attacks on a satirical magazine and a supermarket in Paris, which left 17 people dead.
A French policewoman and three others thought to have links with Amedy Coulibaly, the main suspect of the attacks, have been taken into custody and placed under formal investigation, state-run BBC reported on Monday.
One of the arrested suspects, identified only as Amar, was arrested over drug charges in January, but data collected from his phone showed that he was near the supermarket just before the attack.
Police believe that Amar, a close friend of Coulibaly, may have been carrying out surveillance on the supermarket.
The arrested police officer is Amar’s partner, who was working at an intelligence center in the Paris suburbs.
Police believe that she had access to Amar’s police file following the attacks and passed it on to him.
Police are currently questioning the two other people who had connections to Coulibaly.
On January 7, the Paris offices of Charlie Hebdo satirical magazine were attacked, leaving 12 people dead. The shooting assault was carried out by al-Qaeda affiliates.
On January 9, police ended a hostage-taking at a supermarket in the eastern Porte de Vincennes area of Paris, killing armed hostage-taker Coulibaly, who was also a suspect in the killing of a policewoman in southern Paris a day earlier. Coulibaly killed four hostages before his death.
