Tablet computer thefts at Preston Hedge's Primary School, Northampton
More than 90 computer devices have been stolen from a Northampton primary school.
The break-in happened in the early hours at the 420-pupil Preston Hedge's Primary.
Thieves took four laptops, 62 iPads and 30 LearnPads, specialist tablet computers designed for schools.
Head teacher Paul Watson said he was "disappointed" and urged anyone in the community who had information to come forward and contact police.
Northamptonshire Police said the raid took place between 03:00 BST and 03:40 BST.
Mr Watson said: "We're disappointed because this impacts on our children and our ability to teach the curriculum.
"School is supposed to be a safe, secure environment, so it's distressing that we've had intruders and it was a pretty sophisticated crime as they got in through the roof and the laptops were locked away behind a metal shutter.
"If anybody has any information that might be useful, could they contact the police so that no other school has to endure what we've been through."
The school said none of its desktop computers were stolen and that it was fully-insured for the thefts.
