Fire crews from south east Cornwall helped fight a major blaze on an industrial estate during the night.

The alarm was raised after an explosion on the Pennygillam estate at Launceston shortly before 1.30am.

A witness could see flames coming from a nearby property.

Firefighters from Launceston found three lorries well alight and feared the possibility of spread to nearby buildings.

Crews from Liskeard and Callington and a specialist appliance from St Austell were sent to the scene, where firefighters used four breathing apparatus sets, two main jets and a hose reel to tackle the fire.

Within an hour the situation was under control and crews were damping down.
