GREENSBORO, N.C. -- Greensboro police on Monday released video of a blast that damaged several vehicles and a hotel on Elm Street last night.
Two explosions in the vicinity of 111 W. Washington St. that sent manhole covers skyward occurred shortly after 8:30 p.m. on March 20.
The build up to the first explosion can be seen as smoke emitting from a manhole cover begins to increase in intensity from underneath an unoccupied white vehicle in the center of the screen.
The second explosion was not captured on video.
The Biltmore Hotel, Carolina Theater and the Greene Street parking deck were quickly evacuated at the time of the incident. No one was injured in the incident.
Police cordoned off several blocks surrounding the incident. People were permitted back into the area around 11:30 p.m. after officials determined that the problem had been stabilized and the area was safe.
Greensboro police said in a statement Sunday night they believed the cause of the explosion was related to the electrical infrastructure.
Crews from Duke Energy are trying to determine the cause of the explosion.
Duke Energy released the following statement on Monday afternoon:
"We are continuing to work with local authorities and other utilities to determine the exact cause of this incident. Investigations completed last night and today have yet to reveal the exact cause of the incident or to confirm that it was related to the electrical infrastructure.
"There were no immediate power outages associated with this event. Some customer did lose power for a brief period around early this morning while we de-energized some lines to inspect them for damage."
