New York City police have arrested a man on murder and arson charges in the death of a woman who was set on fire inside a subway train early Sunday morning.

The man accused of killing a City subway rider by setting her on fire has no memory of "what happened" and admitted to heavy drinking, authorities said Tuesday.
