New York City firefighters were investigating a building collapse in upper Manhattan on Wednesday, according to a spokesman for the fire department.

The spokesman said the department was responding at a building at East 114th Street and Park Avenue in East Harlem after reports of a collapse at about 9 am. The fire department said they had no information on casualties or whether anyone was inside.

Television images showed smoke and dust rising from the debris and fire engines spraying water into the rubble.

Commuter trains were stopped on nearby tracks and passengers were ordered off the Metro-North Railroad cars at the Fordham stop in the Bronx, passengers said.
