At least 4 injured in Manhattan scaffolding collapse

A massive scaffolding collapse occurred in SoHo Sunday afternoon, causing at least four injuries.
The incident happened just after 11:30 a.m. near Broadway and Prince streets.
Witnesses say they saw scaffolding fly off the building on the northeast corner. 
Officials say they think more scaffolding could come off the building and are trying to keep the area clear while they work to secure the building.
