PUPILS at a Newton Aycliffe school launched an investigation after a mysterious giant egg appeared in their playground.

The youngsters made the discovery on their return to Sugar Hill Primary School following the Easter break today (Tuesday, April 22).

Pupils are using writing activities to help them solve the case, which is expected to take a week.

Literacy co-ordinator Jennifer McCormack said: “They have already come up with a number of ideas but they will be involved in enquiries to find out where it has come from.”
