POLICE are searching for a cyclist who witnessed an argument which led to a man allegedly driving a car’s wheel over a woman’s foot.

A man and 59-year-old woman were seen arguing on Crossley Road, Thatto Heath.

Police say that during the altercation the man got into a car and drove away but the woman suffered a foot injury caused by the tyre.

He headed towards Thatto Heath Park and neighbours called an ambulance. She was taken to hospital for treatment to a badly bruised foot and ankle.

She was discharged from hospital later that evening.

Detectives are treating the incident as assault and have arrested and bailed a 22-year-old local man.

Police are keen to speak to anyone who saw the incident, which happened at about 5pm on Friday, January 4.

They particularly want to trace a cyclist who stopped at the scene, but left before police arrived.

Contact Detective Sergeant Kirsty Miller at St Helens CID on 0151 777 6811 or Crimestoppers on 0800 555 111.
