A 4-alarm fire Thursday night left massive destruction along a strip of businesses on East Gun Hill Road in the Bronx.

The FDNY says the fire broke out just before midnight in the attic of 1234 East Gun Hill Road, between Pearsall and Throop avenues. It was upgraded to four alarms within 30 minutes, bringing hundreds of firefighters to battle the flames. It took them 2½ hours to bring the fire under control.

The owner of Solid Rock Multigraphics says he's owned this business for almost three decades and says he can't believe this is what's left of his shop.

"Actually, it's heartbreaking because I put 29 years of my life here, 29 years of my life is what is here," he says.

Fire officials tell News 12 one firefighter was hospitalized with minor injuries and is expected to be OK.
