Police have ruled out arson as the cause of the fire that destroyed a popular Wanganui bar last month.
Fire Service officers were called to the Caroline's Celtic restaurant and bar on September 26 but the fire was already out of control when they arrived around 4am. The building could not be saved.
Detective Senior Sergeant Dave Kirby said an investigation into the cause of the fire was done in conjunction with the Fire Service, although police had now stepped back.
"It has reached a stage where it seems that it is not suspicious and so it does not require any further police involvement."
John Hotter, a fire risk management officer, said two possible causes of the fire had been identified.
