A man is dead, two other men and a woman were arrested, and the Serious Incident Response Team is investigating after police say a man accidentally shot himself early Sunday morning in downtown Halifax.

At 4:19 a.m., Halifax Regional Police were called to the area of the Radisson Hotel on Hollis Street for a weapons complaint after four people were refused entry and hotel staff heard a shot fired outside the hotel. After they left, police received information that a shot was fired somewhere outside the hotel.

At 4:40 a.m., police found four people three men and one woman near Barrington and Blowers streets.

When the officers approached the group, one of the men began to run south on Barrington Street. As he was running, a gun went off, apparently causing a self-inflicted wound.

Paramedics transported the 25-year-old man to hospital where he died from his injuries.

Two of the three other people — a man and a woman — were arrested at the scene. The remaining person, a man, was arrested at a Glebe Street address at 5:15 a.m. All three have been released from police custody and no charges have been laid.

The initial gunfire outside the hotel has been referred to the Major Crime Unit for investigation.

SIRT is investigating the man’s death.

SIRT is responsible for investigating all serious incidents involving police in Nova Scotia, whether or not there is an allegation of wrongdoing. A public report summarizing the results of the investigation must be filed within three months after the investigation is finished.

Barrington Street was shut down between Blowers and Salter streets. It reopened Sunday afternoon.
