A sex mad cop who filmed his swinger friends having sex and naked sunbathers from a police helicopter has been slammed by a judge for the “complete and utter violation.”

Adrian Pogmore used a hi-tech camera on board a $5.25 million police chopper to film his pals having an eight-minute romp on their patio.

The 51-year-old also snapped footage of a mom-of-three sunbathing naked and used a powerful lens to zoom in on her and her teen daughters in their garden as his crew mates watched.

He was today slammed at by Judge Peter Kelson QC, who was summing up in the trial of three of Pogmore’s colleagues at Sheffield Crown Court.

The judge said: “This was a complete and utter violation of her privacy.

“She did not know Adrian Pogmore and had every right to expect privacy in her garden, surrounded by tall trees.”

Pogmore, who worked for South Yorkshire Police Air Support Unit at the time, has already admitted four counts of misconduct in a public office but three colleagues deny the offence.

Serving South Yorkshire officers Matthew Lucas, 42, and Lee Walls, 47, retired South Yorkshire Police pilot Malcolm Reeves, 64, and former South Yorkshire pilot Matthew Loosemore, 45, deny being a part of Pogmore’s set ups.

The police helicopter, usually used for capturing fleeing criminals and helping to patrol large groups after football matches, was even flown over a naturists campsite called Candy Farm.

Pogmore decided to zoom in on a naked couple sat outside their caravan.

The judge said the $2.62 million chopper would normally be used to pursue fleeing criminals and cost $59 to keep in the air for two minutes.

A jury were previously shown footage of a woman who was sunbathing fully-naked in her private garden with her three daughters, aged 18, 15 and eight – all wearing bikinis.

Graphic content was also played to the jury when the same crew spotted a couple having sexual intercourse in their garden in South Yorkshire.

Prosecutor Richard Wright QC said the recordings were “not simply the product of one swinging and sexual obsessed air observer Adrian Pogmore but were made with the connivance of the other members of the crew.”

The footage used as evidence in the trial was found in a draw belonging to Pogmore in his desk at a police station.

Walls, of Sheffield, denies one count, Loosemore, of Doncaster, South Yorks., denies one count, Reeves denies one count and Lucas, of Sheffield, denies three counts of misconduct relating to watching and filming naked people without their consent and observing and recording people performing sexual acts.

The charges relate to four alleged incidents between 2007 and 2012 – one on August 23 2007, two incidents on July 28 2008, and one incident on July 22 2012.

The case continues.
