UPDATED: No Suspects, No Evidence of Shooting After Response to Report of Gunman

UPDATE, Nov. 23, 6:58 a.m.: After a long lockdown and search for a reported shooter, authorities found no evidence of a shooting.

"Nothing was found. It's unknown if we actually had a shooting, or if, as other people described it, it was fireworks," said Lieutenant Rob Lamborghini of Glendora Police.

Officers also found no one, or nothing suspicious in the primary house on Cobblestone Way, Lamborghini said.

The containment was finished after 2 a.m. and residents were finally allowed to enter and leave the neighborhood.

PREVIOUSLY: Authorities are still on scene with a large containment at a condo complex after receiving calls of a man shooting at a house in the area of Lone Hill Avenue and Petunia Street.

It is unknown if someone was actually shooting at the home in the area of the 1900 block of Driftstone Drive near Cobblefield Way. One caller stated that a man was shooting at a home from outside with a rifle, according to scanner reports. There is no word on any potential injuries, or if there was a shooter at all.

No description of a potential shooter was immediately available.

Authorities arrived to the residence in question around 6:50 p.m. Police were in full force and have brought in West Covina Police, El Monte Police and a SWAT vehicle, according to scanner reports.

Authorities are confident the home where the shots came from is in the 1900 block of Cobblefield Way.

At least one resident of the area was reportedly out walking around the time of the shots fired call. The resident heard three loud booms and looked up to see aerial fireworks in the sky. It is unknown if the fireworks are related to the call.

Officers on scene have been collecting more information from some of the callers to better ascertain the situation and are attempting to evacuate some homes in the immediate area, according to scanner reports.
