Four people died and eight were injured as a boundary wall of Jal Vayu Vihar society in Sector 21 in Uttar Pradesh's Noida collapsed on Tuesday.
All 12 who had been buried under the rubble at Jal Vayu Vihar in Sector 21 around 10 am were labourers. One person has been arrested so far as per the reports.
Multiple JCBs were deployed to clear the debris of the collapsed stretch of the wall that was located adjacent to a drain, officials said as police and fire department personnel swung into action for immediate rescue and relief measures.
"A total of 12 labourers were pulled out of the rubble. Four of them died while others suffered injuries in the episode," Additional Deputy Commissioner of Police (Noida) Ashutosh Dwivedi told PTI.
Police Commissioner Alok Singh, Joint Commissioner Love Kumar and Noida Authority CEO Ritu Maheshwari reached the spot. Fire service officials, including its chief Arun Kumar Singh, were also there to oversee rescue operations, the officials said.
"The Jal Vayu Vihar society is an old-construction society. The boundary wall was also constructed by the society itself and looked weak," Maheshwari said, further adding that the work on the drain outside the society was being carried out on the request of the society by a Noida Authority contractor through a tender.
"The labourers working on the drain repair came under the wall, which suddenly collapsed. There were 12-13 persons at the spot. Of those rescued, one is injured and the remaining are fine," Maheshwari said.
On the contractor being cautioned by locals that the boundary wall was weak, the Noida Authority CEO said the matter would be investigated.
"A joint investigation by the police, the district administration and the Noida Authority will be carried out and if negligence is found on anybody's part then action would be taken against them.
"The contractor was working on the drain and not the boundary wall," she clarified.
Uttar Pradesh Chief Minister Yogi Adityanath expressed grief over the loss of lives due to an incident. He has also directed senior officials to reach the spot immediately and continue rescue operations on war footing.
The CM's office said, "He expressed his condolences to the bereaved families of the deceased and directed them to make proper arrangements for their treatment while wishing speedy recovery of the injured."
The incident comes just a few days after a wall collapsed in Lucknow due to heavy rainfall, killing nine people.
