My neighbours car alarm is faulty and sounds for hours on end till he turns up and deactivates it. Currently his house is under renovation and he is not living there but the car is left on the drive. Another neighbour has a contact number for him but it is usually hours before the alarm is turned off. Worst case so far is the alarm sounding from Friday evening till Sunday afternoon - although on this occasion the car was in his garage - but it was still annoying. This has been going on for months. As you can imagine I am sick fed up with this and want to know if I have the right to simply smash the window pop the bonnet open and disconnect the battery. Any other suitable suggestions?
