SPRINGFIELD, Ohio -- Surveillance cameras caught a man who walked into a Springfield gas to rob the business.

It happened at the Speedway on South Burnett Road.

Cops say the man told the clerk, "I'm sorry, I have to rob you."

Then, according to police, the man lifted his shirt and showed a weapon, which was a blade from a circular saw.

Lt. Noel Lopez said, "He obviously is not afraid to show the saw and tell the clerk he'd use it. He's a danger to himself and to the employees."

In the video, you can also see the man take off with a fist full of cash.

Employees chased the man, but lost him.
