The plague of gun violence in Surrey has hit home for local Mounties.

The RCMP has confirmed someone opened fire at the Surrey detachment at 104 Avenue and 148 Street, but investigators are still working to determine when the shooting took place.

Mounties said city workers discovered a hole in an exterior window at the building Tuesday morning. It was initially believed to have been caused by a rock, possibly one that had been tossed from a lawn mower, but a bullet was later found lodged in the drywall behind the window.

No other details have been confirmed.

If the bullet was fired within the last three months, it will bring the tally of shootings in Surrey up to 32 for this year, which amounts to roughly one every three days.

Investigators blame the bulk of those on an ongoing drug-related conflict between two new groups.

Anyone with information on any shooting in the city is asked to contact Surrey RCMP or Crime Stoppers.
