AN investigation is under way after two fires at a disused building in Hadleigh.
Firefighters from the town and Ipswich were called to an outbuilding in Calais Street at 7pm on Friday and 8.30am on Saturday.
On the first occasion crews put out the blaze at the brick building using two hose reels after flames spread from the ground floor to the roof.
Firefighters returned to the building the following morning after reports that smoke was seen and the roof was again alight.
A spokesman for Suffolk Fire and Rescue said the fires were being treated as suspicious.
