Yaletown shooting report submitted by IIO to Crown Counsel

B.C.'s civilian police oversight agency says it believes an officer may have committed an offence in relation to the Yaletown shooting in Vancouver last June, and has submitted a report to Crown Counsel.

The brazen downtown shooting occurred near a Starbucks store on Davie Street at Marinaside Crescent​, when Gerald Battersby, 61, allegedly shot bike shop owner Paul Dragan, 52, multiple times.

The Independent Investigations Office's report focuses on the actions of police on Davie Street and in the shootout which ensued, when the suspect exchanged fire with police at the scene, before fleeing on a bike along the seawall.

​The suspect was chased by police to Science World, where another exchange of gunfire behind the building led to Battersby being wounded by bullets to the leg, arm and knee.

Dragan and Battersby both survived the incident. One police officer suffered minor injuries, hit by flying glass when the windows of her car were shot out.

Offence may not be related to shootout

In a statement on Thursday, the IIO said it is legally bound to submit a report to Crown Counsel when, after reviewing the evidence, it considers an officer may have committed an offence.

While Crown Counsel at the Criminal Justice Branch assesses whether to approve charges, no more information is expected to be released, but the IIO says the potential offence may not even be linked to police treatment of Battersby.

"The Police Act does not specify that the offence must be connected or linked to the affected person who was injured or who died," said the statement.

The statement cited one previous example, in which police officers were under investigation by the IIO after a suspect was injured in a fall.

The fall was deemed an accident, but the IIO still submitted a report, considering that the officers may have obstructed justice and given false statements in their reports.

IIO would not say how many police officers they consider may have committed an offence in the Yaletown shooting case, but said the investigation had focused on several different officers involved in the incident.

Battersby remains in custody, facing trial on six charges of attempted murder and several firearms charges.
