A pervert who tried to take pictures of a woman as she undressed in store changing room has been told to complete a sex offenders’ programme.

Marlon Wasniewski was chased down the street by his victim’s fiancee after she spotted him trying to take covert covert photos with a mobile phone in a Wimbledon charity shop.

The 52-year-old from Putney was later found to have hundreds of indecent images on his computer, thought to have been taken in a similar way.

On Thursday Wimbledon Magistrates’ Court heard that on May 8 a 28-year-old woman was trying on clothes in the changing room of Scope on the Broadway when Wasniewski tried to take pictures of her.

She was wearing only leggings and a bra when she spotted a hand underneath the changing room door that was pointing a mobile phone between her legs.

She put her head out of the changing room and saw Wasniewski, who her fiancee chased as he fled from the shop. He was eventually brought back to the store - where he insisted he was not responsible for taking pictures of the victim.

But a police raid found more than 900 covertly-taken photographs of women on his computer, and he later admitted one count of outraging public decency.

Addressing the magistrates from the dock Wasniewski, of Cambalt Road, said: “I really regret the upset I’ve caused - I’ve got nobody to blame except myself.”

He said discussions with the probation services about dealing with his problems had made him think there might be “light at the end of the tunnel”.

He was sentenced to a three-year community supervision order, and ordered to complete a sex offenders’ programme. He must also pay his £85 costs and his victim £200 compensation.
