Daytime break in at Sturminster Newton High School
Mobile phones and iPods have been taken during a burglary at a Dorset school.
A staff member disturbed a man in changing rooms at Sturminster Newton High School at about 17:00 BST on Wednesday.
Police said the intruder made off with a number of "high value" items.
Officers are appealing for anyone who saw a small white car or van and a blue Peugeot car making off from outside the school shortly afterwards.
