Kolawole Oladetoun aged 25, of Leather Gardens, Stratford, London, was found guilty of five counts of exposure and one count of sexual touching following a trial at Harrow Crown Court.

He was sentenced to 23 months in jail and also handed a seven year Sexual Harm Prevention Order on Monday, 15 January.

The court heard how on Sunday, 18 October 2020, Oladetoun boarded a service to Kentish Town and sat diagonally across from a lone 30-year-old woman.

He exposed himself and began masturbating while staring intently at her until she left the service, distraught at what had happened.

On four more occasions spanning throughout the following year Oladetoun targeted more women in a similar way, exposing himself and staring and or grinning at them while he masturbated.

His behaviour escalated on Saturday, 7 August 2021 when he sexually touched a 19-year-old woman as she climbed the steps at Hounslow West London Underground Station.

She immediately turned around and punched Oladetoun who ran off and boarded another train but not before she took a photograph of him and memorised the headcode of the train.

British Transport Police quickly arrested Oladetoun on the train after identifying him from her photograph.

Investigating officer DS Brittany Armstrong said: "Four of the women targeted by Oladetoun demonstrated remarkably quick thinking by taking a photograph or video of him despite being left shaken and terrified of what he may do next. 

"It is in no small part thanks to all the women targeted that we were able to piece together Oladetoun predatory behaviour across the network and ultimately bring him before the courts.

"Their bravery in reporting what happened to them and their help with the investigation should be commended.

"We will stop at nothing and make full use of our plentiful resources to come after those who exhibit this type of behaviour on the network.

"If you experience or witness a sexual offence on the railway, I urge you to report it to 61016 or via the Railway Guardian app. In an emergency, always dial 999. We will always take you seriously."
