A HUGE fire that destroyed the main building at Sheffield Ski Village causing millions of pounds of damage was an accident.
But two subsequent blazes at the facility are being treated as arson.
The main building of the Ski Village was razed to the ground on April 29 in the first of three fires in the space of three weeks.
A second fire was started two days later in the ski lift control tower at the top of the slopes.
Firefighters were called to the centre on Vale Road for a third time on May 21, when grass near the slopes was set alight.
South Yorkshire Police said investigations had shown the first fire, which was initially thought to be arson, was not caused deliberately.
The conclusion was confirmed by South Yorkshire Fire Service, which said investigations into all three fires have now finished.
“The only one that was in contention was the first fire and the smaller ones were deliberate,” a fire service spokesman said.
The fire service confirmed the first fire had now been put down as accidental.
Police said there had been no arrests made in connection to the two fires being treated as deliberate but that investigations were ongoing.
Initially, South Yorkshire Police treated the first blaze as suspicious.
Management at the village have allowed Sheffield Sharks amateur ski club to return to training on the slopes.
South Yorkshire Police said: “It is believed at this time that the initial fire began accidentally, however enquiries are still ongoing. Two subsequent fires were deliberate.”
