POLICE have launched an appeal for witnesses today following a hit-and-run collision in Ipswich.

A red Ford Fiesta SX and a black Audi A4 collided at the junction of London Road and Dickens Road about 10.45pm last night .

The J-registration Fiesta is thought to have been being followed by a plain clothes special police officer in Dickens Road when the crash happened.

It is thought that the occupants of the car recognised the officer and drove away from the junction of the two roads before colliding with the P-registration Audi.

The driver of the Fiesta fled the scene and was chased by an officer who lost him at the railway bridge on London Road.

Police launched the force helicopter and deployed a police dog to the scene in a bid to find the teenager.

The searched the London Road allotments area but could not trace the man, who is believed to be black and aged about 18.

The passengers of the Fiesta did remain at the scene and are believed to be from the Nacton area.

No one was injured in the collision but both cars were badly dented and the Ipswich-bound lane of the road was blocked until 12.10am today.

A spokeswoman for Ipswich police said scenes of crime officers would be looking at the vehicle today to try to establish the identity of the driver.

Although an officer is believed to have been following the vehicle at the time of the collision they were not in pursuit and the spokeswoman said she did not believe the accident had been referred to the force's complaints and disciplinary department for investigation.

No one has been arrested in connection with the incident.

She appealed for anyone with information about the collision or the driver to call Pc Julian Ditcham at Martlesham Roads Policing Unit on 01473 613500 or Crimestoppers on 0800 555111.
