A three-storey building in the Transport Nagar area here collapsed on Saturday, leaving 28 people injured, while five bodies were recovered from the spot.

As the rescue operation continued overnight, teams of the National Disaster Response (NDRF) and State Disaster Response Force (SDRF) recovered three bodies, identified as Raj Kishore (27), Rudra Yadav (24) and Jagrup Singh (35), Relief Commissioner G S Naveen said.

The eighth body was recovered around 3 am on Sunday, officials said.

Joint Commissioner of Police Verma said, "We are now focusing on ensuring that no one else is trapped under the rubble."

"NDRF and SDRF teams are removing the debris and that will take time. The possibility of someone still inside the debris is lower. Had there been someone, their family members would have contacted us by now," he said.

Police said the building was constructed around four years ago and some construction work was underway at the time of the incident. Most of the victims were working on the ground floor when the incident occurred at 4:45 pm on Saturday.

The injured have been admitted to various hospitals in the district, including the Lok Bandhu Hospital.

According to the officials, the building had a motor workshop and warehouse on the ground floor, a medical godown on the first floor and a cutlery warehouse on the second floor.

Akash Singh, who worked in the medical godown and was among the injured, said a pillar of the building had developed a crack.

"We came down to the ground floor because it was raining. We noticed that a crack had developed on a pillar of the building. Suddenly, the entire building collapsed on us," he said.
