Robber on oxygen dies in crash

A man who robbed a New York City store while attached to an oxygen tank has died in a car crash during a police chase, officials say.

Police say the man, identified as 63-year-old Arthur Williams, walked into a Turkish menswear store in Manhattan last Friday with a cane and breathing through a tube connected to the tank.

Police say he fired three shots after demanding money, but fled empty-handed. No one was injured.

Officials say Williams made his way to Maryland where he robbed two hotels early on Sunday.

A description of the robber went over police airwaves and a state trooper, who was following a drunken driver, realised he was pursuing the robber.

After a chase, authorities say the robber ran off the road and crashed into a parked car. He was pronounced dead at the scene.
