A CYCLIST threatened to a stab a driver after a row in the street, police say.

Police are calling for witnesses to come forward following the incident, which happened in Bournemouth Road, Poole at 8.50am on Thursday, December 7.

The driver of a black Honda CRV - a woman in her 40s - challenged a female cyclist who she believed was about to go through a red traffic light.

The cyclist then verbally abused the woman, kicked and punched the Honda, attempted to rip wing mirror from the vehicle and then opened the passenger door and slammed it shut.

After the lights turned green the victim drove away and pulled over to examine her car.

The victim claims she was then approached once again by the cyclist who became abusive, drew a small pointed item from a compartment on the bike and threatened to stab her. The cyclist also rammed her bike into the victim.

The cyclist was riding a turquoise-coloured mountain bike and wore a blue helmet and thermal head cover, trainers, black leggings and a dark pink jacket.

PC Conor Valentine, of Dorset Police's traffic unit, urged anyone who saw the incident take place to get in touch with officers.

“I am issuing a photo of the cyclist which was taken as she rode away and I would ask her, or anyone who knows who she is, to please come forward so we can fully investigate this incident," he said.

“Finally, I would ask any motorists who were travelling in the area at the relevant time and have dash cam fitted in their vehicles to contact us if they have captured the incident.”
