The alleged perpetrator was born in 1986 in Afghanistan and is called Sultan Marmed Niazi.
A knife attack in Villeurbanne, in the suburbs of Lyon, killed one (who was a young man of 19 years) and wounded nine (including three who are in critical condition) this Saturday night, near a subway station.
Stopped by passersby, the attacker is currently in custody. Born in 1986 in Afghanistan according to his statements, Sultan Marmed NIAZI made confused remarks to investigators.
