Man has arm cut off by train but demands glass of water

A man fell asleep on a train track and lost his right arm - but instead of yelling for an ambulance he calmly asked for a glass of water.

Officers found Bobby Joe Medlin, 31, covered in blood close to the tracks in Fort Smith, Arkansas.

He asked for water before they noticed his arm was missing up to his shoulder.

A firefighter found Medlin's arm about an hour later, but doctors said it was too damaged to be reattached.

Medlin, of Van Buren, was earlier involved in a car crash.

He checked himself out of a hospital against medical advice hours before losing his arm.
