TORONTO

The need for photos and video captured by the public during the deadly Muzik shootings is critical because investigators were unable to gather any footage from within the nightclub, the Toronto Sun has learned.

Security video is often helpful in difficult investigations where witnesses refuse to talk, but a source confirms the upscale Muzik Event Centre had no surveillance cameras at the time of the Aug. 4 shootings, which killed two people and wounded three others.

Toronto Police, who have yet to release any images of the suspected gunmen, have chosen not to comment on specifics of Muzik’s security system.

“As soon as we have any information that would be useful to the investigation, we’ll release it to the public,” spokesman Mark Pugash said Wednesday.

On Tuesday, Chief Mark Saunders referred repeatedly to “gaps” in Muzik’s security when he urged more of the 4,000 or so people who were at the club to come forward.

He wouldn’t elaborate on those “gaps,” but they were troubling enough to prompt the service to suspend paid duties for its officers at the club until the problems are resolved.

Muzik, which was reportedly paying the city $10,000 a month as of 2014 to lease the historic Horticulture Building at Exhibition Place, said it’s co-operating fully with police as they investigate the double murder.

But the club would neither confirm nor deny whether it has security cameras.

“It would be highly inappropriate of Muzik to do or say anything that could interfere with a police investigation,” a spokesman said via e-mail. “That includes divulging highly sensitive aspects of our security system.”

Muzik has previously said its security on the night of Drake’s OVO Fest after-party included 10 paid-duty Toronto cops and 73 security staff who searched “every guest” with metal-detecting wands as they entered the club.

Yet somehow a gun managed to end up inside.

Duvel Hibbert, a 23-year-old who was under house arrest for drug charges, was killed on the club’s patio around 3:20 a.m.

More bullets flew moments later outside of Muzik, killing innocent bystander Ariela Navarro-Fenoy, 26, near the Dufferin Gates.

There have been three shootings at Muzik in the past 2 1/2 years.

Police have admitted the hunt for the killers has been slow-going because only a few witnesses have talked.

Pugash said the chief’s appeal on Tuesday prompted several other witnesses to come forward, but there are still thousands who fled the club when the gunfire erupted who have yet to speak to cops.

Anyone with information, especially photos or video, is urged to call the homicide unit at 416-808-7400 or Crime Stoppers at 1-800-222-TIPS (8477).
