Four people have been arrested in a major ‘hit-and-run’ investigation – as it is revealed detectives believe a car was deliberately driven at a schoolboy.

Emergency services, including an air ambulance, were called to High Wycombe at 3.20pm on Thursday after receiving 999 reports that a pedestrian had been hit by a green Vauxhall Corsa in Kibbles Court, in Hennerton Way.

The victim, a 16-year-old boy, was left with a broken leg and was rushed to John Radcliffe Hospital after a group of males from inside the car were seen running away from the scene, police today confirmed.

Detective sergeant Michael Anderson, of Force CID based at High Wycombe, said: "Detectives are investigating this serious incident in which we believe a vehicle has been deliberately driven at a 16-year-old boy. He has been receiving treatment for his injuries.

"This appears to have been a targeted incident however people locally may notice additional officers in the area while we work to establish the circumstances.

"I would like to appeal for anyone who has any information about what happened or who saw anything which could help the investigation, to come forward and speak to officers."

Following the crash, a 15-year-old boy from High Wycombe was arrested on Thursday on suspicion of GBH and was released under investigation.

A 19-year-old man and a 17-year-old boy were arrested yesterday on suspicion of GBH and were released with no further action.

Today a 24-year-old man from High Wycombe was arrested and is currently in police custody.
