Construction worker Mahiuddin was at a building site at Todapur Road near the Pusa Institute in Inderpuri, when a basement wall collapsed and took him under. Two other workers -- Darsun Islam and Mursheed -- were injured in the collapse. The three were rushed to Ram Manohar Lohia Hospital where Mahiuddin was declared `brought dead'. The other two labourers were subsequently discharged.

All the three labourers are from West Bengal and in their mid-20s.

The Inderpuri police is investigating the case.
