The Cobourg Police were dispatched to an address on University Avenue in Cobourg shortly after 7 pm on Friday evening regarding a home invasion style robbery.
Uniform Officers, Forensic Identification Officer, Special Constables and members of the Criminal Investigations Branch attended the scene.
Four males wearing masks, dressed in dark clothing armed with handguns entered the residence.
The suspects allegedly stole cell phones and wallets prior to fleeing the scene.
At this time police believe this was not a random event and that the address was targeted.
Investigators are appealing to any witnesses, anyone with residential video surveillance or anyone driving in the area at the time who may have a dashcam, to please come forward.
This is a developing story.
