Our neighbor's car

I can't believe it happen again.  Someone  broke into our neighbor's car  last weekend, presumably by the same person. This was the second time that it happen . Fortunately, this time  nothing of value had been taken  but the lock of the boot had been broken and unlocking doesn't work anymore. The first time it happen, some of our neighbor's belongings which were inside the car  had been stolen. Our neighbor is a builder and I think he had some tools inside his car at that time. He always park his car in the driveway close to their house but since that incident happened last weekend, he is parking his car now at their backyard.We cannot trust anyone nowadays. Our suburb is  quite, friendly and beautiful. Whoever did it, we really don't know
