Fire investigators say that the fire that destroyed Aardman animations, home of Wallace and Gromit among others, was caused by faulty electronics.

They believe that a faulty water heater or CCTV system was to blame for the fire that destroyed over 30 years worth of props, scenery, models and awards. The two-month investigation found the fire had started accidentally in a ground-floor office.

"The cause of the fire was an electrical fault with an appliance. Arson has been ruled out," a spokesman for the Avon Fire and Rescue service said.
