A Medway teacher was told he faced a long spell behind bars after he admitted sex offences with a teenage girl.

Clive Gibson, who taught in Gillingham, admitted three charges of sexual assault and one of causing a child to engage in sexual activity.

Gibson, 52, of Bredhurst Road, Wigmore, denied a second charge of causing a child to engage in sexual activity in relation to him allegedly asking the girl to strip naked over Skype.

Maidstone Crown Court heard his pleas were acceptable and that the latter offence was expected to be left on file once he was sentenced.

Judge Philip Statman told the father-of-four custody was inevitable.

“I have to assess the level of dangerousness that you pose to children.

“But I want to make it absolutely clear to you that in a case such as this there is no alternative. The only appropriate sentence is one of immediate and substantial custody.”

Gibson, who was supported in court by two of his children, was released on bail with conditions including not to have any contact with children under 18 and not to leave or attempt to leave the UK.

Sentencing will take place on April 11.
