SPRINGFIELD, Ohio -- A robber chose an unusual weapon to hold up a gas station in Springfield.

A man with a circular saw blade tucked in the front of his pants robbed the Speedway at 405 S. Burnett Rd. Wednesday night.  

The man walked up to the cashier and said "I hate to do this, but I'm robbing," according to witnesses.  The man then snatched the cash out of the clerk's hands as he took it from the register, said police.

Police are still looking for the suspect.  He is described as a man with a long goatee and shoulder-length hair, and he was wearing a grey t-shirt and blue jeans at the time of the robbery.
