A disgraced assistant headteacher at a Norfolk primary school has admitted possessing hundreds of sickening child porn images.

Alastair Walker, 56, who was a PE teacher at Middleton Primary School, west Norfolk, admitted one charge of making indecent images of a child under 13 on February 22, 2008.

He also admitted possessing 330 indecent photographs of children on June 15 last year, of which 110 were among the most serious category.

Walker, of The Street, Hindolveston, Dereham, was acting headteacher at Middleton Primary School in 2007 and 2008.

Walker, who appeared frail and was using a walking stick, had his sentence adjourned at Norwich Crown Court to a date to be fixed and a psychiatric report was also ordered.

When the allegations came to light, Walker was suspended from the school pending the police investigation and a statement at the time said that the charges did not relate to any pupils at the school.
