VANDALS destroyed the tyres of at least 25 cars in an area of Liversedge last week.
Damage totalling thousands of pounds was caused to vehicles on Valley Road, Valley Court and Ings Crescent last Thursday night.
A sharp object was used to puncture the side wall of as many as all four tyres on a vehicle.
Some victims reported finding a pinprick hole, suggesting a dart, while others appeared to have been slashed with a knife.
When victim Dawn Foster took her dog for a walk on Friday morning, she spotted flat tyres everywhere.
Dawn, 46, checked her and husband Richard’s cars and found that all the tyres on both vehicles were flat.
She said: “I’m struggling to get my head around what’s happened.
“Some holes look like they could have been made by a dart but others look to have been slashed with a Stanley knife.”
Richard, 45, was able to walk to work without his 57-plate blue VW Polo.
But Dawn, who works in Bradford, had to take a day off to sort out the Polo and her 63-reg grey Ford Fiesta.
The cost of replacing all eight tyres was £600.
They decided not make an insurance claim because of the excess and the chance that their premiums would go up.
“It’s caused a lot of inconvenience and has cost families a lot of money,” Dawn added.
“In our case we’ve used some of our savings, which we wanted to use for the nicer things in life.”
Police stepped up patrols around the area in response to the vandalism.
Insp Mohammed Rauf, of the Batley and Spen NPT, also wants anyone who saw suspicious activity to come forward.
He said: “We have a number of positive lines of enquiry and are working closely with local partners.
“We have increased patrols to reassure residents that this type of behaviour will not be tolerated.”
Anyone with information can call PC Kirsty Stanley on 101, quoting log 209 of Friday May 13.
