From The BBC:
A ten year old Muslim boy who mistakenly wrote that he lived in a "terrorist house" during an English lesson at school has been investigated by police. The pupil, who attends a primary school in Lancashire, meant to say he lived in a "terraced house".
The boy was interviewed by Lancashire Police at his home the next day and the family laptop was examined. The boy's family said they were left shocked by the incident and want both the school and police to apologise.
