During this investigation, allegations emerged that pornography had been found on Green's work computer when he was arrested over leaks in 2008. He said this was a "political smear". The police detective computer forensics expert who examined the computer when Green was arrested rebutted this in early December 2017, stating: "The computer was in Mr Green’s office, on his desk, logged in, his account, his name ... it was ridiculous to suggest anybody else could have done it". In December 2017 the police expert was being investigated by Scotland Yard for keeping copies of confidential material, unrelated to the case he was working on, and then releasing it to the public. Green denied that he downloaded or looked at such images. Green said that the claims made by the retired Bob Quick were "political smears". Metropolitan Police Commissioner Paul Stephenson confirmed that he was informed about the matter at the time but regarded it as a "side issue".
