A man has been arrested on charges he slashed another man on a crowded subway train, police said Saturday. The attack was the latest in a spate of assaults in the city's transit system.

Randy Johns, 41, was arrested on charges of assault, criminal possession of a weapon and criminal possession of a controlled substance, police said.

The slashing occurred late Friday afternoon on a train at 14th Street and Seventh Avenue. Police detained Johns shortly after the incident at a subway station one block away.

The 46-year-old victim was taken to the hospital, where he was treated for cuts to the right side of his face and neck, and later released.

The incident came one day after authorities said a man wielding a cordless power saw in each hand attacked a postal worker at a station on Manhattan's Upper West Side, and two weeks after a Boston man was charged with injuring four people during a stabbing spree in the subway and the city's theater district.
