Police are treating a huge fire that broke out in a derelict building in Ipswich as a suspected arson.

Firefighters were called to the fire in the former Fisons factory in Paper Mill Lane in Bramford just before 3.45pm on Sunday.

A spokesman for Suffolk Fire and Rescue Service said on arrival crews found a three-storey derelict building well alight.

The fire was about 40 by 30 metres in size, the spokesman said.

Police have now confirmed they believe the fire was started deliberately.

Appliances from Ipswich East and Princes Street fire stations were called to the blaze.

Dozens of firefighters were called to a huge fire that ripped through the factory in 2019.
