A vigilante armed with a samurai sword has been filmed coming to the rescue of a man being attacked by two other men in a light rail car in the US.
Mobile phone footage of the October 6 confrontation in Phoenix shows a man being cornered and pummelled by a rain of blows from his attackers.
The men continue fighting as a sword-wielding man unsheathes his weapon and raises it above his shoulders before inching towards them.
As soon as the men see the menacing blade they stop punching and back away from the cornered man who tries to grab the sword, repeatedly saying "let me see it!"
But the wannabe samurai simply raises his fist towards the man as he ushers the attackers out of the carriage.It is not known what sparked the initial confrontation but Phoenix police and rail authorities are investigating the incident.
