A knifeman viciously stabbed a rail user in the neck after he bumped into him at a subway station in the French city of Lyon.
They appeared to share a brief exchange before the attacker chases after the stranger and plunges a knife into his neck.
He then casually walked away, while the victim placed his hand on the wound and looked around in confusion – seemingly unaware he had just been stabbed.
The attacker immediately fled the scene after the attack and police were desperately searching for the suspect.
Meanwhile, the victim was treated by emergency services at the scene and taken to hospital.
One source told Frontières it was a ‘miracle’ the man survived the attack and took just five days off work to recover.
A relative of the attacker is said to have reported him to the police having recognised him when a video of the horrific assault went viral online.
Police then arrested the alleged knifeman on Wednesday night in his home in the Venissieux neighbourhood.
President of Lyon Bruno Bernard made a statement on X on Wednesday night to announce the arrest.
‘Since Sunday, we have been looking for an individual who attacked a user of our metro with a knife following a stampede.
‘This heinous attack quickly mobilized our services, we immediately transmitted our video surveillance images to the police. The individual has just been arrested’, he wrote.
Bernard went on to thank the national police for their ‘rapid’ efforts to investigate the incident.
‘Our thoughts also go out to those who were victims of this act’, he added.
According to local news outlet Lyon Mag, the attacker was already known to police.
