The agency that investigates serious incidents involving police in Nova Scotia will look into how a mentally ill man fell to his death on Monday after officers broke into his apartment.

The Serious Incident Response Team says the 27-year-old left a mental health treatment hospital in the city and police were looking for him.

The agency says officers went to his apartment at about 1:30 p.m., but found the door barricaded, so they broke in.

The Halifax police say minutes later, the man fell from the balcony and he died in hospital later from his injuries
