These are the first pictures from the scene of an alleged murder on a new build estate near Brize Norton.

The front door to a detached property in Lock Court, Brize Meadow, was cordoned off with blue-and-white police tape and is guarded by an officer in a marked patrol car.

A forensics officer could be seen at around 7.20pm emerge from the house and look inside a white Ford Transit van parked outside the house. The 55-plate van did not appear to be a police vehicle.

Earlier this evening, Thames Valley Police’s DCI Jon Capps said the Major Crime Team had launched a murder investigation after the death of a man in his 20s at the property on Monday night.

He said: "We are treating the incident as a murder inquiry due to the reports of a disturbance at the property late yesterday evening, together with witness accounts to date.

“The exact cause of death is yet to be established and we are awaiting results from a Home Office post-mortem examination, which is due to be conducted on Friday.”

The victim’s name has not been released by police.
