A teenager who refused to tell police his computer password was jailed for four months.
Oliver Drage, 19, was arrested by officers tackling child sexual exploitation. His computer was seized but it was protected by a 50-character password.
Drage, a fast-food worker, from Freckleton, Lancashire, refused to reveal the encryption key – an offence covered by the Regulation of Investigatory Powers Act 2000.
Preston Crown Court sentenced him to 16 weeks in a young offenders' institution. Detectives are still trying to crack the code on Drage's computer to examine its contents.
