A Nigerian man identified as Peter Fabiyi, has been arrested after he allegedly pulled down his pants, brought out his manhood and masturbated inside a public train.
According to police in the United Kingdom, 32-year-old Fabiyi of Exmouth Road, Walthamstow, released sperm on a woman during the act.
Fabiyi pleaded guilty to one count of sexual assault and was consequently sentenced to 4 years imprisonment.

According to Mirror UK, the suspect approached the woman on a London Underground train last July.
Fabiyi was noticed by the victim, in her 20s, standing with his trousers undone as the train left Elephant and Castle station in central London.
He then performed the sex act while they were both alone in the carriage.
The victim then pushed past him and frantically fled to another carriage, before telling another passenger what just happened.
Detective Constable Jennifer Brown, who led the investigation, said: “This was a hugely shocking and frightening incident for this woman, and I commend her for having the awareness and courage to report the offence and support the prosecution.
“This sentence sends the clear message that sexual behaviour on trains or at stations is completely unacceptable and BTP will use every method at our disposal to identify people responsible and bring you before the courts – it is simply not worth it.”
