Dave Harrington, a photojournalist for WGRZ-TV, said he heard an explosion as he arrived at the scene of an underground electrical fire Sunday afternoon in downtown Buffalo and a second explosion was caught on camera when it launched a manhole cover into the air in the background of an interview Harrington was shooting with a witness.

The Buffalo Fire Department said a third, smaller explosion was detected about 2 p.m. Investigators said the electrical fire was reported about 11:30 a.m. by witnesses who reported smoke billowing out from manhole covers on Tupper Street. A National Grid spokesman said the cause of the fire is under investigation. "Clearly, there was some kind of a fire down there, but what caused the circuits to burn, we don't know yet," spokesman Stephen Brady told The Buffalo News.
