The tribunal, comprising a deputy assistant commissioner of the Metropolitan Police and two members of the Police Complaints Authority, dismissed the charges against Constable Philip Spittles.
PC Spittles was a member of a vice squad based at Paddington in west London which was disbanded in mid-1988 amid suggestions of misconduct.
The case against PC Spittles stems from a complaint made by Lynda Al-Subaie, a former Military Police officer, who was convicted in 1988 of running a disorderly house. Ms Al-Subaie claimed he had lied when he denied planting a cat-o'-nine tails at her home. She also claimed he and a Superintendent Peter Bean lied about seeing a naked man there.
Following her official complaint, disciplinary proceedings were brought against both officers. They were thrown out by a tribunal last year but reinstated by the High Court after legal action by the authority. Supt Bean retired early on medical grounds.
Ms Al-Subaie's appeal against her conviction and nine-month suspended sentence was postponed pending the disciplinary hearing and is now expected to take place shortly.Reuse content
