The police said the 12-foot boundary wall, which was freshly constructed, collapsed when a tyre of a JCB machine hit it. Six labourers, including four women, were buried under the rubble. Some labourers tried to pull them out. The four labourers died while two others were injured who are reported to be critical.

“We have registered an FIR against the owner of the plot and the contractor,” said Dalbeer Singh, ACP (Mujesar). Later, SDM Susheel Sarwan, Tehsildar BS Rana met the victims at a hospital.
