A detective on Camden and Islington’s sex crime team who faked documents and failed to properly investigate cases has been convicted.

Carl Ryan, who was a member of the Met Police Sapphire Command, faked witness accounts and repeatedly failed to submit evidence for forensic examination.

The 35-year-old, of Cemmaes Court Road, Hemel Hempstead, Hertfordshire, was found guilty of five counts of misconduct in a public office.

He was acquitted of a sixth charge.

He falsified witness statements and caused a victim to be told, and told a suspect’s solicitor that the Crown Prosecution Service had authorised charges to be brought in a case which, at that time, was untrue.

It followed an investigation by the Independent Police Complaints Commission (IPCC).

IPCC Associate Commissioner Tom Milsom said: “Throughout his time leading investigations into allegations of serious sexual offences, Carl Ryan broke the trust of the vulnerable victims he was supposed to protect and seek justice for.

“He deliberately ignored the advice of experienced officers, and failed to submit valuable evidence for forensic testing, instead lying about the results.

“In order to cover his tracks he falsified crime records to manipulate his supervisors.

“His actions can be summed up as a significant breach of the faith the public should have in the police.”

Ryan, was sacked in January 2013, and convicted following a two week trial at Southwark Crown Court.
