Four people accused of using a police helicopter to film naked sunbathers and people having sex have been cleared of misconduct.
South Yorkshire Police officers Matthew Lucas, 42 and Lee Walls, 47, and pilots Matthew Loosemore, 45 and Malcolm Reeves, 64, had all denied misconduct in a public office.
They were acquitted following a three week trial at Sheffield Crown Court.
A fifth man, Adrian Pogmore, 50, had admitted misconduct in a public office.
During the trial, the court heard a couple sitting naked by a caravan were filmed in July 2008, while the aircraft also filmed a garden where a woman was sunbathing naked with her daughters in 2007.
The footage also showed a couple having sex on their patio in July 2008 and at one point, the naked woman waved at the aircraft.
