Winnipeg police are warning the public about two people that have been going around the city pretending to be undercover officers.

WPS said officers not in uniform, but in plain clothes, will have an official badge affixed to their belt directly in front of their sidearm.

They also explained that police vehicles that would be involved in traffic stops will have a combination of red and blue coloured flashing lights, located on either the roof of the vehicle, or mounted behind the front windshield by the rear-view mirror. Also, police said flashing white lights may be located within the front grill.

The safest strategy when approached by anyone in an official capacity is to confirm credentials and identification, WPS said. All officers are required to carry a badge and a warrant card to identify themselves as police officers.
