A former Guantanamo Bay inmate is among six people from an alleged Isis recruiting network who have been detained in France.
Among the suspects arrested was Sabir Mahfouz Lahmar, who was freed from the US detention centre in Cuba in 2009 after France agreed to accept him, said a judicial official.
He was one of six Algerians detained in Bosnia in 2001 on suspicion of plotting to bomb the US embassy in Sarajevo.
The US Justice Department later backed off the allegations, but held the men at Guantanamo for several years. The former French President, Nicolas Sarkozy, agreed to take Lahmar in April 2009 and he moved to Bordeaux later that year.
The French official said Lamar, at 48, is the oldest of the four men and two women who were arrested and said that there were no indications the group was plotting an attack.
Five of the suspects were detained in Bordeaux and one in Paris in a series of raids on Monday.
The Saudi-trained and employed Lahmar was released by Barrack Hussein Obama. More from Department of Defense office for the Administrative Review of the Detention of Enemy Combatants
