Winnipeg police are conducting an internal investigation into why a call for service was cancelled by someone within the 911 Communication Centre — minutes before a fatal shooting on Sunday.

Police Chief Devon Clunis ordered the investigation on Tuesday.

Rustom Vito Paclipan, 23, died after being shot in front of Opera nightclub on Bannatyne Avenue and Main Street.

Staff at the nightclub called police 1:39:36 a.m. about a fight. The callers said they felt the situation may escalate, according to a police news release issued about the internal investigation.

At 1:42:30 a.m., a call for service was generated and entered but at 1:59:45 a.m. the call for service was cancelled from within the 911 Communication centre, the news release states.

At 2:03:13 a.m., the 911 Communication Centre received a call about a shooting at the same location. Numerous emergency services personnel were dispatched and responded.
 
At 2:06:04 a.m. the first police unit arrived on scene and helped paramedics who were already there. Paclipan was rushed to hospital where he died of his injuries.

Clunis wants to know what happened with that cancelled call.

"I think if you call the 911 centre, as we've seen, we will respond. That's why I'm taking the step of ordering this investigation to find out what happened in this particular incident," he said.

The Winnipeg Police Service has put the staff involved in the incident on administrative leave.

911 murders put centre under scrutiny

The 911 Communication Centre came under scrutiny following the slayings of Corrine McKeown and Doreen Leclair on Feb. 16, 2000.

The two sisters had called 911 and police five times over an eight-hour period. They were found stabbed to death by police after the fifth call.

An inquest report into the sisters' deaths found systemic problems within the communication centre, and the police service made numerous changes to its operations in light of the report's recommendations.
