A manhunt has been launched to find a serial sex offender who masturbates in front of women on trains.

British Transport Police has released a picture of Kolawole Oladetoun after he failed to appear at Harrow Crown Court this week.

In his absence he was found guilty on Thursday (July 27) of six sexual offences.

A warrant has now been issued for his arrest.

BTP officers say he is a "clear danger to women and girls" and to not approach him if he's seen but to call 999.

Oladetoun is said to have exposed himself and began masturbating in front of a woman who was travelling on a train through Kentish Town on October 18 2020 at around 9.30pm.

The following year on April 14 he sat opposite a woman travelling in an empty carriage on the Victoria Line and began masturbating.

A month later on May 15 at around 8pm, he exposed himself and masturbated in front of a woman on a train from Clapham Junction to Kew Gardens.

Two weeks later he deliberately sat in front of a woman on a train to Tonbridge and exposed himself and began masturbating.

She moved seats and he continued staring at her while masturbating, BTP said.

On July 1 he sat opposite a woman on a train from Hampton Court and began masturbating while staring at her.

On August 7 2021 at around 12.10am he approached a woman on the stairs of Hounslow Underground station and sexually assaulted her before boarding an Eastbound Piccadilly Line train.

The victim reported this to BTP who intercepted the train at Hammersmith less than half an hour later and arrested him.

Det Sgt Brittany Armstrong said: “Oladetoun is a clear danger to women and girls and we are urgently trying to locate him as soon as possible so he can be returned to court for sentencing.

“We know that as well as across London, he has links to Stafford and Lincolnshire and is known to stay in temporary accommodation including hostels and Airbnb properties.

“We also believe he could have shorter hair than in the picture we are releasing today.  

“I would urge anyone with any information as to his whereabouts to get in touch with us as soon as possible by texting 61016 quoting reference 284 of 28/07/23.

"If you see him, please do not approach him but call 999 quoting the same reference number. Alternatively, you can call 0800 555 111.”
