NEW YORK (CBSNewYork) — Three people were hurt when officials say a driver lost control and plowed into scaffolding outside a building in East Harlem Tuesday afternoon.

Authorities say the driver of a white van lost control and drove into a building near the corner of Second Avenue and 122nd Street, causing the exterior scaffolding to collapse onto the sidewalk below.

Cell phone video captures the chaotic moments following the collapse.

“He lost control driving it,” witness Haidy Melendez said. “He got out of the car asking ‘Oh my God, what just happened?'”

Melendez said the driver was distraught at the sight of an older woman trapped beneath the debris.

The FDNY says three people were hurt, including two pedestrians and the driver of the van. All three were taken to Harlem Hospital.

The wreck damaged a hydrant that sent water spilling into the street. By evening, the van was untangled from the mess and taken away.

Neighbors tell CBS2 the building has been under construction for three years. They say their thoughts turned to the victims injured in the collapse, hoping they’ll be okay.

“It was horrible,” Melendez said. “I was so nervous seeing that.”

The crash remains under investigation.
