PARIS (AP) — A French judicial source says a former Guantanamo Bay inmate is among six people from an alleged jihadi recruiting network linked to the Islamic State group who have been detained.

The official said Tuesday that the suspects arrested in Bordeaux included Sabir Mahfouz Lahmar, who was freed from the U.S. detention center in Cuba in 2009 after France agreed to accept him.

The official spoke on condition of anonymity to discuss the case.

Lahmar was one of six Algerians detained in Bosnia in 2001 on suspicion of plotting to bomb the U.S. embassy in Sarajevo. The Justice Department later backed off the allegations, but held the men at Guantanamo for years.

The French official said Lamar, at age 48, is the oldest of the group of four men and two women arrested.
