He was living in a compound in the town that is the site of one of Pakistan's largest military bases. Given that fact that Pakistan is a military dictatorship, there is zero chance they didn't know he was there. There was constant courier service coming and going for Pete's sake. Even the local kids knew there was someone powerful and very strange living there. They couldn't even get their soccer balls returned when they went over the fence. You think no parents ever complained to the local government or the police about that behavior?
