OTTAWA - Police say a man is facing charges after allegedly robbing an elderly couple of their casino winnings, but losing it in a struggle after the 81-year-old victim chased him down.

Investigators say the couple went to an ATM at an Ottawa bank on Sunday afternoon to deposit their winnings.

They allege a man at an adjacent ATM asked them for assistance and grabbed their money envelope while they were distracted and fled.

Police say the 81-year-old man chased the suspect in his car and cornered him in a nearby alley, where he recovered the money after a brief struggle.

They say a description of the suspect and a cellphone picture taken by a witness aided officers in locating the suspect.

A 44-year-old Ottawa man faces charges that include robbery with violence and possession of property obtained by crime under $5,000.
