A pervert who exposed himself in front of a group of schoolchildren and performed an indecent act has been jailed for a year.

Paul O'Connor, 31, of Bondfield Walk, Dartford, was sentenced at Amersham Crown Court on Friday after he admitted engaging a sexual activity in the presence of a child.

O'Connor boarded the 2.05pm Aylesbury to Marylebone train in June last year when he sat amongst children returning from a school trip.

The court heard he then exposed himself and committed an indecent act.

While none of the children alerted teachers to the incident on the train, several of them reported it to parents when they got home.

CCTV images of O'Connor were circulated by the British Transport Police, which then led to him being identified.

He will now face a year behind bars while he has also been placed on the on the Sexual Offenders Register for 10 years.

Detective Inspector Chris Neeson said: "I am pleased O’Connor has been brought to justice.

"His actions were unacceptable, and it must have been disturbing for these children to have to witness them.

"Thankfully, incidents such as this are rare.

"British Transport Police will continue to work to ensure the rail network remains a safe place for passengers of all ages, free of unwanted sexual behaviour."
