Among the injured is a 7-year-old girl, WNBC in New York City is reporting on its Web site. None of the injuries are life-threatening, according to WNBC.
The building, which houses the former Gristedes supermarket, was being razed to make room for a high-rise apartment building when what was left of the building collapsed.
New York City Fireman Adrian Deronja said the five civilians might have been passers-by. "The area was cordoned off," Deronja said. "Possibly [workers] might have knocked down some of the retaining devices built while they were demolishing it."
WNBC is reporting that all 25 construction workers at the site have been accounted for.
