Police are searching for witnesses after a man drove dangerously and abused a London Ambulance Service staff member during an emergency call in Worcester Park.

Police said the driver of a Honda CRV-type vehicle pulled up behind the ambulance and got out of his car before shouting abuse at a man and a woman in Central Road, near the junction with Green Lane, at around 6.45pm on December 27.

This was while they were responding to an emergency call to help an elderly woman suffering from an acute illness.

London Ambulance Service team leader Katie Vallis said: “It is completely unacceptable for our staff to suffer verbal abuse from members of the public when they are trying to do their job.

"Thankfully, on this occasion, our crew was not injured, but as a Service, we will not tolerate this type of behaviour."

Fortunately neither were hurt and they resumed their shift after the incident while the Honda driver continued on towards Kingston.

Police describe him as a white man, aged in his 40s or 50s, and around 5ft 6in in height.

The man may also have been wearing a green jacket with dark trousers and white trainers.

Police Sergeant John Bouchard from Sutton borough said: "I would urge the man responsible to come forward and speak to police. This is a shocking incident where a member of the emergency services was unjustly abused while on shift, and I would like to think this man will come forward and take responsibility for his actions."

“The CCTV is not of good quality, it is possible that the image, combined with the man’s link to the Honda, may enable somebody to identify him.

"In the meantime, officers will be working to trace higher quality CCTV from buses and information from Automatic Number Plate Recognition (ANPR) systems in order to identify the suspect and the car.”

It is the believed the incident could be connected with an earlier situation where the Honda driver did not move out of the way of the ambulance as it was driving through Worcester Park High Street with its lights and sirens activated.

The Honda driver stated he thought the male London Ambulance Crew member was swearing at him at the time of the incident while he hurled abuse.

Anyone with information should call Sutton police on 101.
