Alarming footage has captured the moment a motorcyclist dangerously sped past a car overtaking a cyclist.

A dashcam video recorded on a Cambridgeshire road shows the man swerve on his bike and gesticulate angrily at the car driver as he passes.

The motorcyclist then slows down and crosses onto the other side of the road to confront the driver before speeding off and overtaking another car on a roundabout.

The shocking recording was taken on the B1050 Hatton Road between Bar Hill and Longstanton on Sunday, June 17 at around 3.20pm.

The motorcyclist had to swerve to get round the car

"I was quite concerned about his behaviour," said the driver who recorded the incident.

"He was all over the road. I thought some of the oncoming cars were going to hit. I didn't know what he was going to do.

"He shot out from behind that car as it was overtaking the cyclist. I don't know how the motorcyclist couldn't have known that car was going to pull out."

The video recorder, who did not want to be named, claimed he had managed to track down the motorcyclist on Facebook after sharing the footage online.

"I found out who he is and made contact with his father who actually defended his actions," he explained.

"His father wasn't interested in dealing with it in any way, shape or form.

"I have a friend who died in a motorcycle accident some years ago.

"I worry about motorcyclists because of that sort of thing happening.

"On this occasion the motorcyclist was most definitely at fault.

"His actions afterwards were completely unacceptable. There's no way anyone should be driving the way he did.

"He must have been a few feet away from oncoming cars that are passing him. It's very dangerous.

"Surely it's only a matter of time before he's in a horrific accident or involves other people in an accident."

The concerned footage taker said he felt someone should "have a word" with the motorcyclist before he "killed himself".

He claimed he described the footage to a police phone operator who informed him that without five minutes of footage recorded before and after the incident they could do nothing.

A spokesman for Cambridgeshire police told Cambridgeshire Live: "Officers need the incident, plus the context, so they can see what happened before that might have contributed to or caused the incident.

"It would be difficult to bring a prosecution without it.

"There is also an issue with it being published because if an incident was investigated and a prosecution brought, the fact it was in the public domain might cause an issue."
