Police investigating the stabbing of a French soldier in Paris arrested a suspect on Wednesday morning whom sources described as an adherent of "radical Islam", reports FRANCE 24.
"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 a statement.
The statement said the suspect was arrested in the Yvelines district on the western outskirts of Paris.
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".
But the sources urged caution in a case that is still in its early stages, saying the suspect was not known to be a jihadist .
The attack on Saturday in a busy underground shopping and transport hub echoed the grisly killing of British soldier in London, but authorities have not yet established a link between the two cases.
Valls told French TV channel Canal+ on Monday that police had "serious leads" on the identity of the attacker, who stabbed and injured French soldier Cedric Cordiez in the neck while he was on patrol with two colleagues.
