A 21-year-old Bedford man has been charged with attempted murder after a string of serious collisions in the span of five minutes in South Harbour on Saturday.

"It's quite an alarming rundown," said RCMP ​Cpl. Andrew Joyce.

Around 3 p.m., police received multiple calls about multiple collisions within a four-kilometre stretch of White Point Road.

"It appears he intentionally collided with three different vehicles — one SUV and two motorcycles and narrowly missing a fourth … before he ended up hitting and penetrating a guardrail," Joyce said.

Thankfully, he said, none of the victims suffered serious injuries.

4 collisions

A Honda Odyssey van first struck an SUV driven by a 49-year-old woman with a five-year-old passenger. The van then fled the scene and hit a motorcycle with two riders.

Soon after, the van then struck another motorcycle with two riders, dragging the bike for a while before driving through an intersection, narrowly missing a fourth vehicle and then crashing into a guardrail.

Two bystanders who tried to help the van driver after the crash were assaulted, police said.

'Some form of intention'

The man is facing several serious charges including attempt to commit murder, dangerous operation of a motor vehicle causing bodily harm, assault causing bodily harm and assault of a peace officer.

Joyce says he can't speculate on the driver's motives, but he says the charges say a lot.

"If you're going to lay an attempt murder charge, there must be grounds for the officers to believe that there is some form of intention," he said.

The man in scheduled to appear in Sydney Provincial Court on Monday.
