POLICE have made another arrest after a 19-year-old man died on Wednesday night. 

Jousha Harling, 19, of Oxford, died of a single stab wound, a post mortem has revealed. 

He was found on Chinnor Road shortly after 7pm.

Eyewitnesses recalled seeing a car on its roof and Thame Fire Station said they had been at a serious collision moments before police and forensics arrived. 

Residents in the area also said they were locked down and police coronds have since prevented anybody from driving nearby. 

Three people have previously been arrested on suspicion of murder - two men aged 19 and a 15-year-old boy. 

Police were granted extra time to question them by High Wycombe Magistrates Court and now tonight, investigators in the Major Crime Unit have made another arrest.

This time another 19-year-old man is being questioned. 

Mr Harling's family are being supported by specially-trained officers.
