Ottawa police have released video footage from an Aug. 12 armed bank robbery to the public in hopes of locating the suspect.

The video shows the suspect quickly pulling out a handgun on a bank employee and then jumping onto the counter and aggressively pointing the gun at the employee.

Police said he left with an undisclosed amount of cash and may have walked to and from the bank for some distance.

Police said the robbery is believed to be related to an earlier bank robbery along the 900 block of Carling Avenue on Aug. 5.

The suspect in that incident walked into the bank at about 9:35 a.m. with a handkerchief over his face and threatened to hurt the employees if they did not hand over cash. He fled with an undisclosed amount of cash and there were no injuries.

He had a moustache and goatee, longer hair and was English speaking, police said.
