One person was found dead and six others wounded on Saturday in the city of Villeurbanne, near Lyon, central France, after a suspected knife attack, a local police source told Reuters.
A suspect who was carrying a knife was arrested while authorities were on the hunt for a suspected second attacker believed to be in possession of a metal spike used to roast meat.
Motivations behind the suspected attack, which was reported to have taken place around 1430 GMT, were not clearly established, the source added.
