NEW YORK (CNN) -- A transformer exploded Wednesday afternoon near Manhattan's Grand Central train station, possibly a result of steam underground, New York Police Department told CNN.
Video from the scene shows what appears to be steam billowing from underground and a small school bus with its windows and a door blown out.
Jim Margolin in the FBI's New York office said there is no indication that there is anything "suspicious" behind the explosion, though the FBI is still collecting information from city agencies and officials.
The New York Fire Department said it received a call reporting an explosion at 5:56 p.m. More than 170 firefighters have been dispatched to the site at Lexington Avenue near 41st Street.
