A 46-YEAR-OLD man has been found guilty of a “serious and foul offence” — after he performed a sex act on a bus in front of a 15-year-old girl.

Clement Kumah will be sentenced today for the offence, which lasted eight minutes and happened on the number 36 bus in Bolton on December 31, 2012.

The jury of nine men and three women took three hours to unanimously decide that Kumah was guilty of engaging in sexual activity in the presence of a child.

After the verdict was given, it was revealed that, in 1996, Kumah was jailed for four years for two offences of indecent assault on women.

He has also previously been convicted for violence against a police officer and assault causing actual bodily harm.

The trial at Bolton Crown Court focussed on the issue of identity, with IT worker Kumah, of Wateredge Close, Leigh, claiming that a man pictured in CCTV images from the bus, was not him.

The images were circulated in The Bolton News and led to Kumah’s arrest several months later.

A 15-year-old girl, who is now aged 16 and cannot be named for legal reasons, was a passenger on the bus from Bolton to Little Hulton on New Year’s Eve, 2012, when the incident took place.

Addressing Kumah, who was remanded in custody overnight, Judge Peter Davies said: “I regard this as a particularly serious and foul offence in front of a 15-year-old girl who was very affected by what happened.

“There will be an inevitable custodial sentence.”
