Appeal to trace car bomb witness

Forensic science experts have examined the car for clues

Police are looking for a man who may have seen a homemade bomb explode in a teacher's car in a school car park.

The blast happened outside Runnymede St Edward's in Sandfield Park, West Derby, Liverpool, on 21 September 2007.

The man was white, about 40-years-old with a stocky build and was wearing a grey tracksuit.

Forensic investigations are still taking place on the vehicle and two men, who were arrested following the incident, remain on police bail.

The bomb was an "improvised firework-type device" and was placed in a Nissan Micra saloon near the school.

The interior of the car, which belonged to a teacher at the school, was extensively damaged and the windows were smashed.
