Vandals have struck again at Standlake's banger racing arena, causing about £2,000 worth of damage.
The latest attack left two toilet blocks and a water tank wrecked as intruders caused havoc with a tractor.
It was the second incident in two weeks at the popular arena, where the May Day Bank Holiday racing attracted about 170 competitors.
Michael Hook, whose son Keith is now promoter, said: "After such a successful day, it left a nasty taste in the mouth."
But Mr Hook is determined the attack will not affect the arena's next event scheduled for Sunday, May 20.
