Police are investigating after a car appears to have had its brakes tampered with whilst parked in Alderley Edge.
The incident occurred some time between 9.15pm on Sunday, 25th March, and 1am on Monday, 26th March, when a silver Toyota IQ was parked on the corner of Lynton Lane and Davey Lane.
The victim only discovered this as she travelled home to Altrincham and her brakes failed.
Sergeant Andy Miller said: "She was not injured and no collision took place as a result, but this could have been much worse.
"This type of behaviour is reckless and could have caused serious harm. We are treating this very seriously and would appeal for anyone with information to come forward. We are particularly keen to speak to anyone who saw someone acting suspiciously around cars in this vicinity.
He added: "It is possible a second car was also tampered with at the time. We would advise that anyone who had parked their cars in this area between Sunday evening and early hours on Monday to get their brakes checked by a garage."
Anyone with information should contact Sgt Miller at Wilmsow Neighbourhood Police Unit on 101 quoting incident number 350 of 26th March 2012. Alternatively information can be given anonymously on the Crimestoppers number 0800 555 111.
