Police are saying little about a major operation yesterday that concentrated on a centre city home.

An ambulance, police cruisers and the forensics unit, converged on the large brick bungalow at 145 Campbell Avenue.

Investigators wearing hazmat suits and protective breathing masks were seen removing materials from the property in boxes and bags.

RNC will only say it’s part of an ongoing police investigation.

VOCM News will have more information as it becomes available.
