A man used his camera phone to take pictures up women's skirts on the tube.

Robert Bayliss, 50, was given a three year community order after being caught red handed by undercover British Transport Police officers.

Bayliss, of Granville Close, Croydon, was sentenced at South Western Magistrates Court on February 23 after pleading guilty to two counts of outraging public decency.

Bayliss was seen standing closely behind a woman on the escalators by undercover BTP officers at Victoria Tube station on September 27 last year.

He was arrested and officers found over 100 similar images on his phone.

A Sexual Offences Prevention Order (SOPO) has also banned Bayliss from carrying any type of photographic equipment on the whole of the rail network for five years.

He was also given a three-year supervision order and will sign the sex offender’s register for five years.

BTP Police Constable Claire Sheals, said: “The officers were on a pro-active patrol looking for pickpockets when they noticed Bayliss acting suspiciously on the escalator.

“Bayliss was arrested immediately and officers searched his phone, revealing over a hundred indecent images.

“BTP deploys plain clothes officers on the Tube network to look out for this kind of rare but disgusting behaviour.”

"Although this type of offence is not common, it is completely unacceptable.”
