New Delhi, July 23 - A 25-year-old labourer was killed and two others were injured when a concrete mixer truck toppled over them at a construction site in the Jawaharlal Nehru Stadium where work was under way for the 2010 Commonwealth Games.

The truck fell sideways after the soil underneath it became soft due to rain at the multilevel parking construction site around 12.10 p.m. Three men who were working at the site came under it.

Sunil from Jharkhand was declared dead at the All India Institute of Medical Sciences while the other two - Nepal, 40, and Muktilal, 45 - were said to be recuperating in the hospital.

The police said the truck was positioned on the edge of a tunnel that was excavated around 10 feet to construct the boundary wall.

'We have registered a case of negligence against the driver and the contractor in the Lodhi Colony police station,' said a policeman.
