It's official, Shiv Sena leader Sunil Shitap caused the collapse of the Siddhi Sai building in Ghatkopar, killing 17 and injuring 25 residents. A 32-page prepared by a civic inquiry panel states that it is beyond any doubt that the unauthorised construction work carried out by Shitap at the ground floor was the trigger for the collapse, hence he is solely responsible for the loss of the life and property in the tragedy. The report has also highlighted negligence by the local ward engineers and health officer, and recommended disciplinary action against them.
