A SEX pest who groped a pensioner on a bus has been ordered to undergo treatment and stay away from his traumatised victim.

Brian Calvert, from North Yorkshire, was warned by a judge that if he offends again, he should expect a prison sentence.

Calvert, 61, was cautioned three years ago for taking a woman down an alley in his home town of Northallerton and fondling her.

In October last year, he struck again on a bus between Thirsk and Northallerton after he sat next to a 71-year-old woman.

Prosecutor Nicholas Worsley told Teesside Crown Court yesterday that there were many empty seats, yet Calvert ignored them.

He began touching the woman’s legs and putting his arm around her, but she knocked his hands away when he tried to feel her breasts.

Mr Worsley said the victim had to endure with Calvert’s attentions for the 30-minute journey while other passengers just watched.

In a statement, she said: “It has affected me a lot.

“I won’t use the bus at all. I now feel scared about going out of the house.”

Calvert, of Bilsdale Close, Romanby, admitted sexual assault and was given a 12-month community order with supervision.

His barrister, Ian West, said he needs help on a sex offender treatment programme to show him what is right and wrong.

“He is 61 and needs to begin to understand that this sort of behaviour is unacceptable,” Mr West told Judge Gillian Matthews.

The judge told Calvert: “This was an extremely frightening and shocking incident which makes her anxious about public journeys.

“Your behaviour was forceful and threatening and is completely unacceptable, and I think you know that, despite what you say.

“It is very concerning you seem to have targeted this lady for your own sexual gratification.

“This may well erode her confidence.

“The Probation Service is offering a package based upon the sex offenders’ treatment programme which is suitable to your needs.

“It should be clear to you that you were cautioned last time, this time you have come to court, and a court will not tolerate this sort of behaviour.”
