A police officer died from a gunshot wound to the chest, a post mortem has found.
The 43-year-old constable, from the Metropolitan Police's Specialist Protection Command, which guards the Prime Minister and other high profile figures, was found at a residential address in Camden on Tuesday.
His death is not being treated as suspicious and detectives are investigating whether a police gun was used.
He was not under investigation as part of either the "plebgate" probe or the inquiries into alleged phone hacking and corrupt payments to public officials.
An inquest will be opened at St Pancras Coroner's Court on Monday.
