New Delhi, July 12 - Minister of State for Urban Development Saugata Ray Sunday said the government will try to find out the reasons for the collapse of an under-construction bridge of Delhi Metro in the capital which claimed five lives.

'Our department will undertake a review and find out the causes. This is a very unfortunate incident,' the minister told reporters here.

Ray also said that all precautions will be taken to prevent such incidents in future.

In one of the worst accidents involving Delhi Metro, an under-construction bridge in a congested area of south Delhi collapsed early Sunday, killing five people, including an engineer, and injuring 15 others.

The bridge was part of an elevated section of the Delhi Metro Rail Corporation's (DMRC) new route on the Central Secretariat-Badarpur section. The incident took place at around 5 a.m. at the construction site at Zamrudpur, near Amar Colony, when a launching girder along with a portion of the bridge set up on pre-fabricated pillars collapsed.

The section was slated to be open September 2010, a month before the Commonwealth Games next year.
