Ottawa Police are investigating a third robbery involving an elderly woman in the Carlingwood Area on May 20, 2014.

On Tuesday, an 85-year-old woman was walking along Iroquois Avenue when a suspect approached her from behind, grabbed her purse and then fled through the Carlingwood Mall parking garage.

The suspect is described as a white man, standing 5'10" with short dark hair.  He was wearing a black shirt and black pants.
