An exterior wall at 270 West 123rd Street in Harlem collapsed around 3:15 p.m. WCBS 2 reports the building was "partially under construction" and "appears to be a five-story walk-up with a pizza shop, Pizzaria 123, on the bottom floor." WABC 7 says that some pizzeria customers were temporarily trapped: "Workers were pouring concrete at a construction site when the wall collapsed into the pizzeria next door." Four people were injured; the extent of their injuries is not known.
