Suffolk Fire and Rescue Service has released the latest findings from investigations into the cause of the fire in Sudbury town centre on September 6.
The initial findings into why the pagers of several Sudbury firefighters failed have also been revealed, the failure causing Sudbury crews to arrive at the fire after the Long Melford engine.
It is believed the fire started in Celebrities Nails in Market Hill.
A spokesman for the Service told the Free Press: “A great deal of work has been carried out to establish the cause of the fire and particular attention is being placed on the kitchen of the nail bar.
“The fire starting in this area cannot at this stage be discounted and materials have been taken away for forensic analysis.”
When asked about the pager failure the spokesman added: “The Service has commissioned testing of the aerial and pager infrastructure at the station and the signal strengths in the Sudbury area – these were all found to be working well.
“At this stage the cause of the alerters not operating has not been established and further investigation is taking place.
“All the firefighters at Sudbury have been issued with new, upgraded pagers, these have been tested and are working satisfactorily.”
