Portland police said Thursday that a 45-year-old Portland man, who was shot and wounded Tuesday night on Oxford Street, remains in critical condition at Maine Medical Center.

Lt. Robert Martin, spokesman for the department, said police are continuing to investigate the circumstances of the shooting.

Martin said investigators have identified all of the parties who were involved in the shooting, but as of Thursday no one had been arrested and the victim’s name has not been released.

Police are continuing to interview witnesses, but are asking anyone with information regarding the incident to contact police at 874-8575.

The shooting took place on Oxford Street near Elm Street around 10:30 p.m. Tuesday.

A Portland police officer was in the area of the Oxford Street Shelter at the time – an emergency shelter for homeless adults – when he heard an altercation and gunfire.

The officer ran to the area and administered first aid until the victim could be taken to the hospital. At the time of the shooting, the man’s injuries were considered life-threatening.

The shooting occurred in the Bayside neighborhood where law enforcement and residents have grappled with unruly street behavior involving fights and illegal drug use.

Portland officials are considering relocating the Oxford Street Shelter to a parcel of land at the Barron Center campus on Brighton Avenue, near the city’s border with Westbrook.
