A Indian British has pleaded guilty of taking explicit pictures of women in public places after police caught him in the act, a media report said.

He was caught when two off-duty police officers spotted him photographing a mother nursing her child in a park.
A search of his phone and computer found over 9,000 images he had secretly clicked, including pictures of women using the toilet and breastfeeding.

The pictures were taken between January 1, 2013 and April 16, 2015. Patel pleaded guilty to one count of outraging public decency.
Judge Susan Cooper adjourned his sentencing until September 9. The judge said the defendant could be facing jail.
