Robert Pitman, 24, has admitted starting the fire that badly damaged Waitrose last summer. He changed his plea to guilty just a few hours before facing trial for arson at Taunton crown court.
The judge told Pitman, who has been in prison on remand since July, that it was pure luck that no one had died in the blaze.
Pitman’s defence barrister told the court that Pitman had no recollection of starting a fire in a waste bin near the store but accepted the prosecution case that it had been him. The court heard that Pitman, of High St Wellington, has a history of black-outs and memory loss.
He will be sentenced on February 7th after psychiatric and other reports on him are complete. The judge warned Pitman that he could face prison.
