Nine demolition workers were injured Monday morning when a building collapsed at a defunct steel factory in Baltimore, police said.
Sixty five personnel from the Baltimore County Fire Department responded to the Bethlehem Steel Plant after reports that the roof had collapsed with workers inside around 10 a.m., according to Baltimore County Police.
Four of the nine who were injured brought to the shock trauma facility at the University of Maryland Medical Center with serious to critical injuries, while five others were transported to local hospitals, police said.
Everyone in the building was accounted for, said Natalie Litofsky, a Baltimore Police Department public information specialist.
The cause of the collapse is under investigation, police said.
