Thieves have stolen a number of expensive computers from Ralph Allen School in Claverton Down.
The intruders broke into the school earlier in August, and stole the 11 older version iMac computers.
Though the incident took place in the first week of August, Avon and Somerset Police are only now appealing for information from the public.
The offenders broke in through the windows of a music room in the building to steal the computers.
As they are the older models of the Apple iMac computer, they only have 15 inch screens making them easily identifiable.
It is believed they were stolen between 7pm on the 1St August and 7am on the 2nd August.
Anyone with more information about the theft, or who has been approached by anyone offering the computers for sale, is asked to contact DC Tony Swift at Bath’s Manvers Street Police Station on 101 or contact the Crimestoppers charity anonymously on 0800 555 111.
