Police are investigating after a smash and grab break-in at the Museum of Barnstaple and North Devon overnight. Officers were called out in the early hours of this morning (Monday) to reports of the burglary after alarms sounded at the museum. It is understood the offenders forced entry to the museum shortly before 2am and smashed a number of display cabinets. They made off with two limited edition Royal Mint collections of gold coins, thought to be worth around £15,000. Scenes of crimes officers are still at the scene this afternoon and it has not been confirmed yet if anything else has been stolen. Alison Mills, manager at the museum, said she was called out by key-holders at 2am today. She said: They stole golden coins which are of significant financial value. Theyve also caused a lot of damage to some exhibits as well as to the window and the wooden cabinets. They were in and out in a matter of minutes, it was a smash-and-grab type raid. The police were very quickly at the scene and we have had to close while they gather evidence. As soon as the police are done and we can clean up the broken glass we will obviously try and re-open to the public. Check back for more as we have it.
