Drury responded to the claims by giving an interview to the "News of the World" claiming he and Humphreys were searching for Ronnie Biggs, one of the gang members involved in the 1963 Great Train Robbery. He also stated that he was paying Humphreys as an informant. The accusation he was being paid as a "grass" angered Humphreys, and he gave a press conference to say that Drury was lying. On 2 March 1972 Drury was suspended from duty by Sir John Waldron, the Commissioner of the Metropolitan Police; Waldron also instituted an investigation into the allegations made by "The Sunday People". Drury resigned from the force on 1 May 1972.
