Thieves drove a stolen car into Willenhall Memorial Park for the second time in as many days at the site, damaging a bench before dumping the vehicle in the pool.
Police were called to the site, in Pinson Road, following reports that a car was being driven into the park from the Aston Road.
A stolen Vauxhall Astra was then discovered dumped in the pool at the rear of the grounds after a search which involved the West Midlands Police helicopter shortly before 5am yesterday.
The vehicle had been stolen overnight from Monmer Court in the Short Heath area. It has now been impounded by officers and forensic inquiries are continuing.
Councillor Carl Creaney, of Willenhall South, said: “It’s twice this week we have had cars being driven into the park.
“This is the fourth time that a car has been driven into the park and then just dumped here. The yobs responsible for this need to think about the devastating effects their actions are having on the owners of the vehicles and on the wildlife.
“It is getting beyond a joke now. I would appeal to members of the public to contact the police with any information.”
Last November a Land Rover was driven through the Aston Road entrance smashing through metal gates causing thousands of pounds worth of damage.
