The Link School caters for 148 students aged from 4 to 18 with Speech, Language and Communication difficulties.
This includes children on the autistic spectrum.
A spokesperson for the school says they’ll provide a statement at the end of the week, but they did confirm it is affected.
Link is part of the Orchard Hill College and Academy Trust.
Other schools under the academy umbrella include Dysart School in Surbiton and Bedelsford School in Kingston.
There is no reason to believe any of these schools are affected.
