An independent school in Norfolk is being investigated by social services officials after a routine inspection raised concerns.

Banham Marshalls College near Diss caters for 120 children with a range of special educational needs, of whom 90 are boarders.

Norfolk County Council said in a statement that inspectors from the National Care Standards Commission had become "concerned that some practices were not appropriate" when they visited in January.

Lisa Christensen, director of Norfolk Social Services, said inquiries were at a very early stage and she could not give further details about the issues raised.

Children's welfare

The headmaster of the school, which is currently on extended half-term, has refused to comment.

But the mother of a nine-year-old autistic pupil told the BBC she was full of praise for the school.

Ms Christensen said her staff were working with the school authorities and were keeping parents informed of the inquiry.

"Clearly, the welfare of children always comes first and we will take whatever action is needed to ensure their well-being."

The school caters for pupils aged between seven and 16 who have emotional and behavioural problems, speech and language difficulties and specific learning difficulties.

It has some places for children with mild autism and Asperger's Syndrome.
