Two 15-year-olds got more than they bargained for while jokingly “ghost hunting” at One Punggol after hearing a mysterious laugh that sent them running. The teens started filming themselves as a joke, pretending that they were “ghost hunting”. In the video, one of the teens can be heard talking as the pair walk through the dark rooftop area. “Both of them instantly knew something was wrong and started running away from the rooftop,” the Stomper said. Whatever the explanation, the mysterious laugh was enough to bring the pair’s joking “ghost hunt” to an abrupt end.
