Curious Incident triumphs at Oliviers

A play about a boy with Aspergers Syndrome has triumphed at this year's Olivier Awards.

The Curious Incident Of The Dog In The Night-Time, based on the best-selling book by Mark Haddon, picked up seven awards, including Best New Play and Best Actor for its star Luke Treadaway.

It tells the story of a 15-year-old maths genius trying to solve the killing of his neighbour's dog.
