One man is dead and another in critical condition after an apparent double shooting in Halifax Friday night.

The incident happened at 8:40 p.m. on Clifton and St. Albans streets. A witness told CBC News that two people had been shot. Two ambulances attended the scene, but only one went to the hospital.

A woman was led away by police as she shouted, "I want to see him."

Const. Brian Palmeter said police are investigating a homicide after responding to a weapons complaint on Clifton Street.

"The investigation is in its early stages. Though the medical examiner has not yet determined the cause of death, police are treating this incident as a homicide," he said.

He said the second victim had non-life threatening injuries.

The Queen Elizabeth II Health Sciences Centre went into lockdown around 9:30 p.m. A spokesman said that happens when there are concerns for the safety of staff and patients.

Neighbours said the house was known for drug dealing.

A police forensics unit is on the scene at Clifton Street.
