A burglar broke into a Norwegian grammar school - and solved some maths problems.

Nothing was stolen in the raid on a school in Klaebu, reports Aftenposten, quoting Adresseavisen.

But the intruder did take on a mathematics test intended for third grade students.

And, according to local law enforcement officials, he - or she - did a good job, solving all the problems correctly.
