Cricket club officials have issued a warning to others after suffering a second burglary in a matter of months.
A gang of thieves used vehicles to smash through metal fences at Horsforth Cricket Club before breaking into a lock-up containing grounds keeping equipment.
They stole about £2,000 of kit.
Chairman Kris Lilley said: “It’s sickening. We’re a volunteer club relying on the hard work of people who give their time for nothing.
“It’s going to cause us a few issues with the season coming up and we’re somehow going to have to find the money to replace what we’ve lost.”
It is thought the thieves used two or three vehicles to demolish the fences before tying a chain or rope to the doors of a shipping container standing on the outfield to rip them open.
They then escaped across the cricket field with an aerator, a blowing machine, a power washer and a strimmer.
The incident, which happened overnight last Monday, is the second time in the space of three months that the club has been targeted.
On the previous occasion, the thieves moved security lighting and used heavy-duty cutting equipment to steal equipment.
Other clubs in the area are also believed to have been broken into.
Mr Lilley added: “It seems too coincidental for it to have happened twice to us in a matter of months for it not to be the same people. For a small club like ours, the loss of a few grand of machinery is a big loss.
“We just want to warn other clubs to be on the look-out.”
Anyone with information should call police on 101.
