The headmaster of a former Norfolk boarding school is facing a whole life prison sentence after admitting sexually assaulting young boys in the 1970s and 1980s.

Bryan Greenhalgh, 63, previously of Suffield near North Walsham, pleaded guilty to 13 counts of indecent assault and one count of a serious sexual offence at Norwich Crown Court today.

The charges related to eight male victims under the age of 16.

The majority of the offences took place at two former independent schools - Sheringham Court School in Norfolk and Thurlby Manor School in Lincolnshire - between the 1970s and 1980s.

Greenhalgh was remanded in custody to reappear at Norwich Crown Court for sentencing on Friday, May 23.

He was warned by Judge Nicholas Coleman that there was a 'real risk' of a life sentence.

Investigating officer Detective Constable Tristan Coull, of Norfolk Constabulary's Child Abuse Investigation Unit, said: 'Greenhalgh is a dangerous individual who exploited his position as headmaster to win over the trust of the boys in his care and subjected them to horrendous abuse.

'He clearly preyed on boys who were at their most vulnerable and who at the time of the abuse felt unable to speak out as he appeared to be an upstanding pillar of the community.

'Through the position he held, it would have been the most basic of expectations to protect these children, instead he chose to do the complete opposite.'

A spokesman for Norfolk police said the force is committed to working with partner agencies to prevent child sexual exploitation, support victims and bring offenders to justice.
