Norwich Magistrates’ Court was told bar staff at a Norwich venue were alerted to CCTV showing a man kissing and fondling a girl who was “very obviously a person under the age of 16” in an encounter lasting 30 minutes.

Stone, of Rushmore Close in Norwich, had previously pleaded guilty to sexual activity with a child.

He appeared in the court dock with an overnight bag expecting to be sentenced before he was told his case was being committed to Norwich Crown Court.

The court heard his offence was categorised as “high culpability" and a “serious abuse of trust”.

It was aggravated by a previous jail sentence in 2015 for possession of indecent images of children and two subsequent breaches of a Sexual Harm Prevention Order( SHPO).

Magistrates said his case was too serious for their powers.

It carries a sentence of up to three years.

He will be sentenced in the week of March 23.
