A partial building collapse in the Bronx Tuesday morning killed one person and injured five others.

Officials say they responded to the scene of a scaffolding collapse on East 208th Street around noon. The FDNY chief of operations says it appears the workers were on the second floor when the third floor collapsed on top of them.

Firefighters then climbed into the building to rescue the workers inside.

One worker died after being trapped inside the rubble, according to the FDNY. The FDNY says three workers suffered minor injuries and were able to walk out of the building. The FDNY says two others sustained serious injuries.

"He was my uncle and we don't know what happened. They were saying that he went to the hospital. They said they were working here, so we came very sad and we don't know what to do. We're trying to figure out what happened to my uncle," said a family member on scene.

After investigating, the city's Department of Buildings was able to determine that the third floor was overloaded with masonry blocks, causing it to collapse on the construction workers below.

The city's Department of Buildings released a statement saying, "This was a preventable tragedy and our hearts go out to the family of the worker who died. No building is ever worth a person's life. We will continue to investigate this incident aggressively and bring all appropriate enforcement actions against those responsible."

According to a sign posted, the new building was supposed to be completed by next summer. The work was being done by Pioneer General Construction Company.

The DOB says there were no violations at the construction site prior to the incident.

News 12 has reached out to Pioneer General Construction Company and has not heard back yet.
