A former member of the U.K.'s Royal Marines, bailed by a court last week over allegations of assisting Hong Kong's intelligence services in a Chinese-linked espionage case, has been found dead, British police said Tuesday.

Matthew Trickett, 37, was found dead in a park in Maidenhead, west of London, on Sunday following a report by a member of the public, Thames Valley Police said.

Trickett was more recently employed as an immigration enforcement officer and private investigator, the U.K.'s PA news agency reported.
