An officer cadet has been found dead in her room at Sandhurst military academy, police have said.

The unnamed 21-year-old was discovered on Wednesday at the academy in Berkshire.

It is understood she was spoken to after failing to return to her barracks following a party on the base over the weekend. But aside from the minor disciplinary incident, there was no suggestion of further wrongdoing.

Thames Valley police were treating her death as unexplained and not suspicious.

A spokesperson said: “At around 3pm on Wednesday officers were called to the Royal Military Academy in Sandhurst. On attending the scene they found that a woman in her 20s had sadly died. Her next of kin have been informed.”

A file was being prepared for the coroner, the spokesperson said.

The Ministry of Defence said: “We can confirm that an incident has occurred at Royal Military Academy Sandhurst, resulting in the death of an officer cadet. Our thoughts are with the family at this difficult time.”

Sandhurst is the training centre for all officers in the British army, and was attended by Princes William and Harry.
