At least 5 people taken to hospital after 3-alarm fire in Easton, Pennsylvania, officials say

Flames broke out at a multi-story building in Easton, Pennsylvania, on Friday, drawing a response from multiple fire departments in Northampton County.

Crews were called to a "high-occupancy" building on the 400 block of Northampton Street, around 10 a.m., for a three-alarm fire.

Northampton County dispatch says at least five people were taken to the hospital in unknown conditions.  

A resident, who said he's lived in the building for five years, tells CBS News Philadelphia his boss alerted him to the fire. 

"My boss called me up. I work for the guy, so he called me up and said, 'Mike, where are you?' He said, 'You better get out because the building is on fire. When I opened my door, I couldn't even see. Nothing but black smoke," he said. "The building is gone, it's collapsed. The whole back of the building, I know, is gone."

Due to the fire, power is out in parts of Easton and the city says that Met-Ed is working to restore it.

Because of the fire, the state theater across the street has canceled its show Friday night.

There's no immediate word on the cause of the fire.
