'The contractor always becomes a soft target. I won't comment more than this. Let's wait for the inquiry committee report,' Umesh Gupta of Gammon India said.

A section of the elevated rail track that Gammon India was constructing to connect the Central Secretariat with Badarpur in the far south collapsed at Zamrudpur Sunday, killing six people and injuring 15.

On Monday, five other people were injured at the same site as three cranes and a launching girder toppled over.

The central government has assured action against those responsible for the accident.
