TWO loud explosions led police in Darlington to investigate on Wednesday night.

Numerous callers from all over the town contacted The Northern Echo after hearing the successive bangs around 7pm.

A spokesman for Durham Constabulary said they had been inundated with calls from concerned members of the public and on investigation found the source to be the town's railway museum, Head of Steam, which had been holding a fireworks display to announce the arrival of the Tall Ships at Hartlepool.
