CCTV images of a primary school break-in have been released.
The footage shows the early morning raid on Upshire Primary School, in Upshire Road, Waltham Abbey, on Wednesday.
Burglars broke into the school grounds at around 3.45am by cutting the padlock on the main gates before opening a window to the school’s IT suite, where they stole 16 laptop computers worth £300 each.
One of the images shows one of the gang lying on the floor to avoid being seen by a passing car.
At around 4am the men escaped in a car which pulled up outside the school.
The incident follows an attempted burglary made at the site in December as well as a break-in at Epping St John's C of E School in Bury Lane, Epping, on December 2.
Anyone with information can contact Essex Police.
The police have not yet revealed if any arrests have been made.
