The age of a secondary school pupil is being investigated amid claims he could be as old as 30.

It is thought that the pupil at Stoke High School in Ipswich is an asylum seeker who joined at the start of last term.

Another pupil at the school posted a photograph of him on Snapchat with the comment: “How’s there a 30-year-old man in our maths class.”

A spokesperson for the school said: “This is a matter for the Home Office and we have referred it to them.

“The student is not attending the school at this time.

“We cannot comment further on an individual case, but we have followed government and local authority policies and guidance, as we do for any admissions matter.”

A Home Office spokesperson said: “We do not routinely comment on individual cases.”

If there is a doubt about someone’s age as part of an immigration case, the Home Office can arrange for social workers to undertake an age assessment.
