Police investigating the stabbing of a French soldier in Paris have arrested a suspect who sources describe as an adherent of "radical Islam".
"The suspected perpetrator of the attack on a soldier Saturday evening in La Defense (business district) was arrested this morning," Interior Minister Manuel Valls said in Tuesday's statement.
Sources close to the investigation said the 22-year-old man has been a follower of a "traditionalist even radical Islam for the last three or four years".
