A 28-year-old labourer died as the lintel of a three-storey showroom collapsed in Sector 118, TDI City, here on Monday evening.
The deceased has been identified as Jaswinder Singh of Chuharmajra near Landran.
Three others sustained minor injuries. Aerocity residents Uday Paswan (42), Karan Kumar (30) and Kuldeep Paswan (25) were rushed to the Phase-6 Civil Hospital.
Locals said the lintel of the second floor of the showroom was being laid when the lintel of the first floor collapsed, trapping six workers in the rubble. Locals raised an alarm after which the trapped workers were rescued.
The supervisor and two workers reportedly ran away from the spot.
Tehsildar Arjun Grewal and SP (Rural) Manpreet Singh reached the spot and oversaw the rescue work.
"An inquiry will be conducted and action taken. A technical committee is probing the Sohana building collapse and the report will be submitted soon," Grewal said.
Two youths had died as a gym-cum PG accommodation at Sohana village collapsed on December 21 as digging work was being carried out illegally.
