A former counter-terrorism officer with the Metropolitan police has pleaded guilty to 19 charges of voyeurism.
Police Detective Inspector Neil Corbel posed as a pilot to secretly filmnaked models he had arranged fake photo shoots with.
According to prosecutors, he concealed spying devices in phone chargers, an air freshener and glasses to film his unsuspecting victims in hotel rooms, flats and AirBnBs.
The offenses are said not to be linked to his job as a police officer.
Corbel will reappear in court on October 4 for sentencing.
Corbel, 40, committed these offenses in London between January 2017 and February 2020.
He was caught when one of the models he had recruited for his voyeuristic habits discovered that the digital clock in the room she was staying in was actually a spy camera.
After his arrest, police found images of 51 women on his hard drive. Of the women who were identified, 19 were willing to make statements against him.
Det Ch Supt Marcus Barnett, whose team carried out the investigation, said he was disappointed in the behavior of this officer of the law.
I am truly disappointed in the actions of the officer which are not at all representative of the high values and standards we expect, and I am saddened by the pain and hurt that he has caused.
Prosecutor Babatunde Alabi told the Westminster Magistrates' Court, Corbel’s victims included escorts and models who -apart from one- did not give their consent to be filmed. The prosecutor said:
He set up the rooms well in advance with covert devices planted in strategic places capturing the women while they were undressing before the shoots. (He)went to quite extraordinary lengths to hide what he was doing.
He has been on suspension at the Met but with his guilty plea, misconduct proceedings will now take place.
