A balcony attached to the top floor of a four-storey building collapsed on a crowded Burrabazar Road, killing a youth and injuring an elderly man on Tuesday evening.

Vishal Mandal, 18, was standing in front of the building at 15 Noor Mahal Lohia Lane when the balcony collapsed around 7.30pm on Tuesday.

Police said the balcony was close to 30ft in length.

“The young man who was standing right under the balcony got trapped under the debris. He was rescued and taken to SSKM Hospital with head injuries. He died of injuries later at night,” an officer of Burrabazar police station said.

Mandal used to live in the same neighbourhood.

Mahabir Sharma, 65, who lives in the same locality, was a few feet from the spot where the balcony crashed. A tile ricocheted and hit Sharma in the leg. He had to be admitted to SSKM Hospital.

The building comprises offices and commercial establishments. There was no one in the office on the top floor when the balcony collapsed, the police said.

“Otherwise more people could have been injured,” an officer said.
