A speeding car ran over labourers working on a roadside, killing four of them and leaving an equal number of them injured on the Safdarjung flyover here in the wee hours on Monday.

While descending from the flyover, the driver of the Honda City car, who was suspected to be under the influence of alcohol, lost control and ran over the labourers, killing two on the spot at around 2 am. Two others died at AIIMS while others have been admitted to the hospital, police said. The driver is absconding. Police are questioning two of his friends.
