A CHIPPENHAM man has been found guilty of sexually abusing a teenage girl during a hands-on martial-arts lesson.

Karate black-belt Brian Hanna, 47, lives with his mother in Plymouth at weekends and with his wife in Chippenham during the working week.

He was convicted of abusing the 15-year-old in a dark icehouse on a Corsham industrial estate where he worked as a full-time handyman.

On Friday Alan Fuller, prosecuting, told Gloucester Crown Court the girl was at a school sex education lesson discussing inappropriate behaviour when she let slip that Hanna had abused her.

Mr Fuller said: "She said this defendant touched her during karate lessons and taken photos of her intimate areas.

"On another occasion he asked her to kiss him intimately. She said it was disgusting, like Pinocchio's nose."

She also described being taken to a cave, which was the icehouse on the industrial estate.

Defending his actions grey-haired Hanna told the jury that he had touched the girl but never with a sexual motive.

He said: "I have touched her breasts, but not in a sexual way."

He said he was teaching the girl the art of punching and blocking when it happened: "I threw a punch at her stomach and she wasn't quick enough to block it and my hand rested on her top, but only for a second."

Hanna maintained the girl had been following him around making advances but Judge Martin Picton convicted him of sexually touching the girl.

Hanna was also found guilty of inciting a child into sexual activity and committing sexual activity with the 15-year-old.

When the verdict was given he looked down and shook his head while members of his family sobbed in the public gallery. He is due to be sentenced on July 6.
