A pervert has been captured on CCTV taking pictures up a woman's skirt inside a south London branch of Boots.
He can be seen bending down as the shopper continues to browse the items - who is blissfully unaware of the photographer beneath.
Despite being challenged by a security guard on his way out of the store, he was allowed to leave the chemist.
The incident happened in a branch of the high street chemist in the Tandem Centre, Colliers Wood, south London, police said.
Today Scotland Yard launched an appeal to trace the man seen on CCTV carrying out the voyeuristic act shortly after noon on November 5.
The suspect is in his 20s and is seen wearing a white t-shirt. Police said he was described as a slim, white man, 6ft tall with short brown hair and blue eyes.
At the time of the incident he was said to be wearing navy blue tracksuit bottoms and brown shoes.
Contact Merton Police on 101, quoting image 195987, with any information.
