1 dead in illegal construction site collapse in Brooklyn: 'They should not have been doing this work'

One person has reportedly died after a basement floor collapsed at an illegal construction site in Brooklyn on Friday.

The incident happened just after noon at a home located on 50th Street in Borough Park. 

According to the FDNY, three people were working in the building's cellar when the first floor collapsed, pinning one of the people.

The victim, a construction worker, was pronounced dead at the scene.

A search throughout the rest of the building found no other victims or structural damage. 

Officials said the work at the site was being done illegally. 

Department of Buildings Commissioner James Oddo said that a complaint about the site had been issued in December, but that inspectors were unable to get access to the site.

Inspectors returned in January and saw excavation being done and issued a stop work order. 

"There are absolutely no plans submitted to the Department of Buildings, so this fatality absolutely should not have happened. They should not have been doing this work let alone having a Bobcat [a piece of construction equipment] inside this structure," Oddo said.

An investigation into the collapse is ongoing.
