THIEVES tried to crack open a cash machine at the Post Office in Cavendish Square, but failed and left their stolen tools behind.

Police said the break in happened at 5.30am on Saturday, setting off the alarm.

The burglars failed in their attempts to break open the ATM and it is though they were disturbed and fled the scene. A number of tools were left behind and it is not believed anything within the store was stolen.

PC Emma Keatings said: “An investigation is being carried out into this incident and inquiries already carried out have ascertained that the tools left at the scene have originated from a high value theft in another force area where approximately £20,000 of tools were taken. They included hydraulic metal cutters, crow bars and screwdrivers. They will be returned to the owners.

“We are keen to hear from anyone who was in the Cavendish Square area early on Saturday morning and in particular, we are keen to hear from anyone who saw two men running towards the rear of the Post Office carrying a black satchel, or any vehicles driving away.”

Witnesses should call 101 or Crimestoppers on 0800 555 111.
