A LIT firework was thrown into a vet's surgery in Appleton during the early hours of Tuesday morning.

The alarm was activated just after 1am on October 15, when a firework was inserted into an air vent at the side of the building, on Dudlows Green Road.

The firecracker landed in the main operating area - shattering glass and causing some minor damage to equipment - and narrowly missing oxygen cylinders. Animals are usually kept in the surgery overnight but they were not injured during the explosion.

Police are treating the incident as criminal damage, but say that it had the potential to be quite nasty.

Anyone who witnessed the incident, or who may have information, should contact PC Paul Whitehead on 652222.
