A doctor pleaded guilty in Britain on Friday to using a secret camera hidden in his wristwatch to film himself sexually assaulting female patients.
Davinderjit Bains, 45, admitted that he assaulted 30 women at his practice in southern England.
The Indian-trained doctor filmed the attacks on his high-definition Tieex Spy Watch, which has been compared to a gadget from the James Bond films.
He admitted a total of 39 charges -- 13 charges of assault by penetration, 13 charges of voyeurism, 11 charges of sexual assault and two charges of sexual activity with a child.
He asked for a further 65 offences to be taken into account when the judge passes sentence.
Police branded Bains a "sexual predator" and said he had covertly filmed more than 100 women.
The offences were committed against females aged between 14 and 51, from July 2010 until May 2012.
The doctor came under investigation when one woman told police she thought he had filmed her as she showered and said he had sexually assaulted her.
Detectives found the wristwatch when they arrested Bains at his surgery and later recovered 361 video clips from the gadget and his computer.
Detective inspector Mark Garrett, who led the investigation, said Bains had used his position as a family doctor to abuse women.
"They put their trust in their doctor and Dr Bains breached that trust massively -- compromising his professional position -- and breached that trust to the highest order," he said.
"Today he stands exposed as someone who has utterly betrayed that trust for his own sexual gratification.
"He is a sexual predator, simple as that. And he was allowed to abuse his position of trust and offend for two years."
Bains qualified as a doctor at Mangalore University, on India's western coast, in 1993 and became a family doctor in Britain in 2007. He is currently suspended from practising.
His surgery said it was "appalled" by Bains' crimes.
"This has been a shocking and distressing case for all concerned," it said in a statement.
