James Arthur George Gathercole was found guilty of two counts of exposure, at London Inner Crown Court.
He was sentenced to two years eight months in prison and he has to pay victim surcharge of £228.
Gathercole was also given a 10 year Sexual Harm Prevention Order where he cannot:
· Travel on the Underground Railway network or enter any Railway Station unless he has notified his allocated offender manager.
· Approach, follow, touch or make any attempts to communicate with any lone female (previously unknown to him).
· Undo, loosen, or remove, totally or partially, any item of clothing below the waist, whilst in any public place.
· Touch himself in any way that would be considered lewd or obscene.
The court heard how Gathercole committed two incidents of exposure on board trains on Sunday, the 26th of May.
The first at occurred at 3.20pm on the train from Motspur Park Station to Wimbledon Station when he sat opposite the victim, a woman aged 27, and proceeded to masturbate and expose his penis in the eye line of the passenger facing him.
Later that evening at 7.20pm Gathercole again boarded a train at West Sutton Station towards London Blackfriars and sat down on the train knowing that the victim, a 19-year-old woman, was in eye line and proceeded to masturbate and expose his penis before getting up and walking through the carriage.
After viewing CCTV, and a video that one of the brave victims was able to record of the incident, the investigating officer was able to identify Gathercole as the suspect.
He was located and arrested where he was subsequently charged and remanded to attend Court where police say he had little option but to plead guilty.
