French policewoman and 4 others arrested in connection to attack

A French police woman has emerged one of those linked to Amedy Coulibaly, the gunman and hostage-taker at a Parisian kosher supermarket, who have been arrested, CNN reports.

3 others have also been arrested in connection to the attack.

The policewoman worked at the Fort de Rosny-sous-Bois, which is the location of an important intelligence center, police spokesman said.

Following an attack on the office of the French satirical magazine Charlie Hebdo, Coulibaly killed four hostages in the grocery store before police shot and killed him.

France has been under a heightened state of alert since January's terror attacks in Paris that killed 17 people.
