Between 4am and 4.17am on Thursday, December 27, Swallow Dell Primary School in Blackthorn Road was broken into.

A staff member returned to the locked school after the Christmas holidays to find that the glass entrance door’s lower panel had been smashed.

The offender(s) appear to have walked into multiple rooms and forced open staff lockers with a tool.

It is unknown if any items were stolen.

PC Rhianna Ward, who is investigating, said: “I’m appealing for anyone who was in the area between the times stated and believed they saw anyone acting suspiciously to get in touch.

“A security alarm was triggered and continued for about 15 minutes, so you may have heard it if you live nearby.”

Anyone with information is asked to contact PC Ward by emailing rhianna.ward@herts.pnn.police.uk or calling the non-emergency number 101, quoting crime reference 41/70821/18.
