Fire crews will investigate the cause of a suspicious fire that swept through a derelict building in the early hours.

The blaze, which is believed to have been started deliberately, broke out at 12.45am in a derelict building on the Elton Park Industrial Estate, off Hadleigh Road, Ipswich.

A fire crew from Princes Street called for backup from the station after arriving at the scene to find one end of the 50m by 10m building well alight, with the added potential danger of asbestos sheeting.

They were able to bring the blaze under control and both crews will return to the scene this morning.
