Unsuspecting female commuters appeared on an adult website after a perverted pharmaceutical expert secretly recorded ‘upskirt’ clips on his phone.
Father-of-two Sanjayan Nadarajah, 43, followed young women wearing short skirts on the London Underground with his phone secreted in his laptop bag.
He also recorded women half-naked trying on clothes in shop changing rooms and took further opportunities to film in airports and shopping centres.
The pharmaceutical quality consultant, who has a chemistry degree and lives in a £775,000 home in Shelvers Way, Tadworth, Surrey was hunted down by British Transport Police (BTP).
Officers discovered the online clips and traced Nadarajah - known as ‘MonkeyMan9’ - when the adult site shared his email address.
At Highbury Corner Magistrates Court yesterday he pleaded guilty to five counts of outraging public decency between May 17 and July 19, last year.
Nadarajah also pleaded guilty to two counts of voyeurism between January 1 and May 12 and was sent on bail to be sentenced at Blackfriars Crown Court on a date to be fixed.
Prosecutor Mr. Nikhil Khosla told the court: “The BTP learned videos were appearing on a pornography site of covert ‘upskirt’ recordings on the London Underground in which the females involved were unaware.
“The person responsible seemed to be using a camera in a bag and on occasion filmed himself.”
There were 57 clips uploaded by Nadarajah under his ‘MonkeyMan9’ username and all but nine, marked as only available to ‘Friends of User’, were viewable.
“Some of the clips were recorded in supermarkets and airports and under changing room curtains of females wearing only their underwear,” added Mr. Khosla.
During the investigation eleven more clips were uploaded after Nadarajah filmed up women’s skirts on an escalator at Lakeside Shopping Centre, plus more on the Underground.
He was arrested on October 9 and police seized a Samsung phone, plus two SD cards containing more ‘upskirt’ recordings.
“These were filmed at close range and Nadarajah could be seen adjusting the camera.
“Examples include a young woman on the Underground wearing a short black and white skirt, who was filmed from behind on an escalator.
“Another was a female sitting opposite the defendant on a tube train, who was wearing a short skirt, who the defendant followed off the train and up stairs filming her buttocks and underwear.
“At a clothing shop in Wimbledon he twice filmed women in changing rooms, with one in full view in just her bra and knickers.”
Nadarajah claimed it was a relief to be caught. “He admitted secretly filming in public places on his phone and that he was ‘MonkeyMan9’ and had also filmed in the Sutton area,” added Mr. Khosla.
“He said it was a fascination for him to film females, knowing they would be in a state of undress and that if they knew they were being recorded they would have felt victimised.
“He said he got sexual gratification from ‘upskirting’ and chose to upload them to the site so he had somewhere to store them.”
The prosecution claim the offences fall into Category One for sentencing purposes with a starting point of six months imprisonment and will also apply for a Sexual Harm Prevention Order.
Magistrate Liz Blake announced: “These matters are very serious. They do cross the custody threshold. The powers of this court are not sufficient.”
