A FIRE which badly damaged at derelict bus depot in Sunderland was started deliberately, investigators believe.

Fire fighters attended the former Arriva bus depot on Riverbank Road in Southwick at about 7pm tonight.

A fire had broken out in a pile of rubbish in the centre of the building, which is about 60m by 30m in size.

In total five appliances attended the fire at the building, which was severely damaged throughout.

Four jets were needed to put out the fire and special saw was used to gain entry through the roller shutters. An aerial ladder was also used to break roof lights to help with ventilation.

"The cause at this time is suspected arson," said a Tyne and Wear Fire and Rescue Service spokesman.
