Police say they’re not treating the death of a man accused of helping the Hong Kong intelligence service as suspicious.

Immigration enforcement officer Matthew Trickett was found dead by a member of the public in a park in Maidenhead on Sunday.

He’d been charged under the National Security Act for offences including information gathering and surveillance.

Mr Trickett was formerly employed by the UK Border Force at Heathrow Airport, before joining Home Office Immigration Enforcement in February.
