This is the horrifying moment a man was stabbed in the neck by a stranger after accidentally bumping into him in a subway station in France. The chilling encounter took place shortly after the attacker disembarked a train at the Guillotière metro station in Lyon on Sunday. The pair appear to share a brief exchange before the attacker chases after the man and plunges a knife into his neck. The attacker immediately fled the scene and police are now desperately searching for the suspect, Frontières media reported. Meanwhile, the victim was treated by emergency services at the scene and taken to hospital, it added. #paris #attack
