Police are canvassing the area of Brybeck Crescent after reports of a sexual assault on a four-year-old girl over the weekend.
On Tuesday, officials released stills from a surveillance video of a person they want to speak to in connection to the incident.
A media release on Monday described the suspect as a white man, between five feet, 10 inches and six feet tall.
He was wearing a white baseball hat and grey striped shirt.
Police say they're looking to identify the man in the photo "in order to determine if he is related to the incident and/or can provide further information."
A command post has been set up in the area while police continue their investigation.
Residents in the area say they're in shock at what happened.
"It just blows me away that something like this could happen to her," says neighbour Sonya McGoey. "Parents try to be vigilant but it only takes a split second."
One woman, who says she lives across the street from where the alleged incident happened, says she saw a little girl leaving on a stretcher.
