A foot overbridge near Mumbai's landmark Chhatrapati Shivaji Maharaj Terminus railway station collapsed this evening, killing four people and injuring 28. The overbridge was under repair but it was still in use. The collapse took place around 7.30 pm -- the busiest hours of the evening, when footfall was at its highest. The Railway Ministry has said the overbridge was under the control of Mumbai's civic body, the Brihanmumbai Corporation - Sena lawmaker Anil Desai has denied the claim. State minister Vinod Tawde said both Railways and the civic body would investigate the matter.
