A teenager has been locked up for 30 months after committing a sex offence against a vulnerable 14-year-old girl.

Dominic Middleton, 19, was sentenced at Carlisle Crown Court today, having previously admitted one charge of sexual activity with a child. It took place on a single occasion.

The court heard of the "profound" impact of the crime on Middleton's young victim.

His lawyer, Keith Thomas, asked for any term of custody to be suspended.

But Judge Peter Davies concluded he was unable to take that step and imposed an immediate 30-month custodial sentence.

"It is too serious, the girl was too vulnerable and the consequences on her are too great," said Judge Davies.

Middleton, of Greystone Road, Carlisle, must sign the sex offenders' register indefinitely. He was also made subject to the terms of a sexual harm prevention order for 10 years.
