Investigation against over 600 people accused of stashing money abroad illegally is going on and a report on it will be submitted in time, Chief of Special Investigation Team on black money Justice M B Shah said. "We have already filed the first report (on black money) in August. Certainly I am hopeful about it (timely submission of second report)," he said. On a day the attorney general submitted a list of 627 names having accounts in HSBC bank, Geneva, to the apex court, Shah said that the list was already known to the team. "Investigation is going on. Without investigation it is very difficult to say that a person is guilty or that person has done something wrong. A person is required to be heard first," he said.
