Quad bikes worth £50,000 have been stolen from a shop in north Worcestershire.
They were taken on Sunday evening from Ace ATVs, in Stoke Pound, near Bromsgrove.
The thieves used cutting equipment to cut through security locks then escaped with the bikes on two of the company's trailers.
Murray Boss, the shop owner, said it was not an opportunist crime.
"Several people have been here with cutting apparatus and they've cut around the locks and removed six large quad bikes and two children's motor cross bikes.
"They're just totally irresponsible people who don't really care about other people's property."
A £5,000 reward is on offer to anyone who can provide information leading to the return of the bikes.
