PARIS (AP) — French police and security officials say four people are in custody over links to the attacks that terrorized Paris in January, including a policewoman.

The two officials, who spoke Monday on condition of anonymity because the investigation is ongoing, said one man who was detained had ties to Amedy Coulibaly, the gunman who killed a policewoman on Jan. 8 and then four more people at a kosher supermarket Jan. 9 before being killed by security forces. They said the man's girlfriend, a policewoman, was also in custody.

The officials had no details about the two others in custody. No one besides three dead gunmen have been linked directly to the Jan. 7-9 attacks at the satirical newspaper Charlie Hebdo and the market, which left 20 people dead, including the gunmen.
