It's a real "who" dunnit.

Penticton RCMP have a mystery on their hands. 

In the early hours of Thursday morning, RCMP responded to an alarm indicating broken glass at a Front Street business. 

Upon arrival there was no broken glass but the perp left behind an impression on the exterior window that police are hoping will help identify the perp. 

If you give a hoot, police ask, and are able to identify the culprit, please contact Cst. Ian Wolchok of the Penticton RCMP.
