Aylesbury murder inquiry over fatal attack
Police have begun a murder inquiry after a man attacked at a property in Buckinghamshire died in hospital.
Mark Austin, 53, was seriously assaulted during an altercation at Harcourt Green in Aylesbury shortly before 01:00 GMT on Thursday.
He was taken to Stoke Mandeville Hospital, where he died on Friday.
Police said a man, 49, arrested shortly after the incident on suspicion of GBH has since been sectioned under the Mental Health Act.
Det Ch Insp Kevin Brown said, "The murder investigation is at a very early stage. However, the victim and the suspect knew each other and this was not a random attack."
Mr Austin lived at Coxhill Way, Aylesbury.
