Ottawa police are asking for help to find a man suspected of robbing a senior at an ATM on Valentine’s Day.

A 74-year-old man asked for help to use the ATM in a building on the 100 block of Rideau Street around 5:45 p.m., according to police.

The suspect was last seen running on Nicholas Street. He is described as being a tall, white man between the ages of 23 and 28. He was wearing a dark coloured jacket with a logo on the front and a Yukon-style winter hat at the time of the robbery, police said.
