An armed man is on the run and two people are dead after they were found with fatal bullet wounds inside a suburban home.

Homicide detectives are investigating after reports of a fight between a group of people at a home in Rye, on Victoria’s Mornington Peninsula, shortly after 4am on Monday.

Police believe a man and a woman arrived at the home and became involved in an altercation with the residents.

The 29-year-old man who lived in the home and a woman who was visiting – who’s yet to be formally identified – were found with gunshot wounds.

“Despite the best efforts of emergency services to revive the pair, they were declared deceased at the scene,” police said.

Another man left the home before police arrived and the search for the gunman is underway.

Homicide Squad detectives are keen to speak to anyone who may have information, CCTV or dash cam footage in relation to the incident.
