Dunston Primary School headteacher Sharon Davison broke the news about the burglary, which happened between 9pm and 10pm on Sunday, to pupils on Monday, October 6.

She said: "You can see in the children's faces and body language that they're really saddened by it.

"I'm sickened. We're trying to do our best for these children by putting on extra activities but now we'll have to put the plans on hold."

Thieves smashed a glass panel in the main entrance of the Newbold school and forced open a hatch to the school office.

They raided cupboards and drawers before escaping with hundreds of pounds – money from a fun run in July – set aside to buy playground equipment.

Mrs Davison said: "We're desperate for outdoor toys for the children. If anyone can donate any equipment, we'd be really grateful."

The raiders also got away with cash and cheques from parents to pay for a school trip to the panto at the Pomegranate Theatre, in December.

Letters have gone out to parents advising them to cancel the cheques and monitor their bank accounts.

Derbyshire Police were alerted to the burglary by a member of the public who heard noises coming from inside the school and saw a dark van parked outside on Sunday night.

A police spokesman said a scenes of crime officer had been at the site looking for clues.

Anyone with information about the break-in should call Derbyshire Police on 0845 123 3333 or Crime-stoppers on 0800 555 111.
