A man who tried to rob a bank in northeastern Colorado Springs on Monday escaped, police said.

Colorado Springs police were called to 4190 Austin Bluffs Parkway shortly before 3 p.m. after a man entered a Chase Bank and slid a note to a teller demanding cash and threatening that he had a gun, although no gun was seen.

The cashier was behind a bulletproof separator and refused to give the man any money, police said.

The man ran out of the building eastward, but police did not catch the suspect.
