Chicago police have arrested a man who allegedly robbed a bank using a threatening note written on the back of his own pay cheque.

Police say 40-year-old Thomas Infante walked into the bank and gave a staff member a note saying, "Be Quick...Give your cash or I'll shoot".

He got $400 (£270), but left behind half of his note as he fled.

Detectives found the rest of the slip - complete with his name and home address - outside the bank's front doors.

Mr Infante was later arrested at his home in Cary, Illinois. If convicted of bank robbery, he faces up to 20 years in prison.
