The fake MI5 ID card which the court heard belonged to Marcus Alder
A former policeman who pretended to be a secret agent has been convicted of a string of offences, including fraud and firearms offences.
Peterborough Crown Court heard Marcus Alder, of Offord Darcy, Cambridgeshire, had a fake MI5 identity card and drove a BMW with the registration MI5 SPY.
Jurors convicted the 48-year-old of perverting the course of justice and perjury as well as the other offences.
Jurors have yet to return verdicts on two charges and the trial continues.
The court heard Alder pretended he had been the gay lover of a wealthy friend in a effort to claim a share of the dead man's fortune.
He faked a suicide note after finding Philip Tyssen-Gee dead in Somersham, Cambridgeshire, in 2006 and tried to trick relatives into giving him at least £100,000, jurors were told.
Police later found a note that Alder had written on a computer in which he said: "I am just after Phil's money. It's true, I am a dodgy git but definitely hetero."
