A music teacher faces jail after admitting hiding a pinhole camera in his office and bathroom so that he could film girls undressing.

Christopher Bell, 38, of Dowding Road, Norwich, admitted making indecent photographs of six girls aged between 12 and 15 over a ten-year period.

He also admitted voyeurism after Norwich Magistrates Court heard how he filmed three adult women undressing in his bathroom.

Bell, who was released on bail, is due to be sentenced by a crown court judge at a date to be fixed.

Douglas Mackay, prosecuting told magistrates that Bell had committed the offences between 1996 and 2006. He said he had persuaded one 13-year-old girl to change in his office in preparation for a school musical production then filmed her using the hidden camera.

On an internet biography Bell told how he came from Colchester, Essex, was a member of the St Paul's Cathedral choir as a child and sung at the wedding of the Prince and Princess of Wales in 1981.
