Police have dropped an investigation of a 10-year-old Muslim boy who mistakenly wrote that he lived in a "terrorist house" rather than a "terraced house" — a British term for row houses.

The boy's school had notified authorities about his statement because of a law requiring schools to report any possible links to extremism.

Lancashire Police said in a statement Wednesday that a police officer and a social worker visited the boy at his home in Accrington because of the misspelling.

Police said: "There were not thought to be any areas for concern and no further action was required by any agency."

The boy's name has not been released.

The BBC reported that the boy's family were left shocked by the incident and they have demanded an apology from police and the school.
