Police believe the third fire in as many weeks at Sheffield’s Ski Village was started deliberately, after a slope was set on fire on Monday.
South Yorkshire Police suspect the latest attack was arson and said criminals thought it was “open season” at the ski village.
Firefighters were called to the outdoor attraction on Vale Road at 7.50pm on Monday and managed to control the blaze.
The latest fire means the village has been engulfed in flames on three seperate occasions in three weeks.
Investigations are still continuing into the cause of the first fire which destroyed the village’s main building on 29 April.
A second blaze on 1 May, which gutted the facility’s ski lift, is believed to have been started deliberately.
Anyone who witnessed any suspicious activity in the area should call South Yorkshire Police on 101 quoting incident number 1093 of the 21 May 2012, or call Crimestoppers on 0800 555 111.
