A woman who crashed a motorbike into a car driven by the former commander of City of London Police and then assaulted him has been banned from driving for six months.

Maidstone Magistrates’ Court heard Rosie Smith, from Tunbridge Wells, was riding a Yamaha TT through High Brooms last June.

Mark Kateley, prosecuting, said a number of defendants had appeared in front of the courts over the past few months charged with various offences linked to the incident at 3pm on Powder Mill Lane.

He said former commander Wayne Chance was off-duty and with his husband in an Audi A4 heading towards Southborough when a motorcycle clipped a corner and veered into the driver’s side of the car.

Neither the bike rider nor female pillion, who both ended up on the ground, were wearing crash helmets.

Mr Chance got out of his car to help but after attempting to pick up the bike Smith, 39, ran off.

The teenage passenger attempted to flee but Mr Chance grabbed hold of her.

Smith returned with Shardayne Austen and grabbed the girl’s other arm.

Mr Chance told her he was a police officer and the girl was under arrest but Smith responded, “no she’s not she’s coming with us,” and dug her nails in to his arm, drawing blood.

During the fracas the teenager managed to slip out of her jacket and run to a nearby Nissan Qashqai. Mr Chance gave chase but the car drove off.

Mother-of-three Smith insists she was not involved in the initial collision and only lashed out in self-defence when she came to the aid of the girl.

She was convicted of assault, driving without due care and attention, while disqualified and without insurance and must now pay £50 compensation and adhere to a two-month curfew between 9pm and 7am.
