If you heard a ‘boom’ and saw a flash Sunday night, you’re not alone. But Bend police could not find the cause

BEND, Ore. (KTVZ) -- Bend police investigated several reports of a loud explosion and a flash of light on the south end of town Sunday evening. They tell KTVZ News that officers searched the area but found no evidence of property damage, injuries or criminal activity.

Deschutes County 911 dispatchers received several calls around 8:30 p.m. regarding a loud bang and a visible flash. Sheila Miller, Bend police communications manager, said that while multiple people reported the event, officers were unable to find the source of the noise or flash.

KTVZ News inquired after a viewer who lives in the Romaine Village area off Brookswood Boulevard told us, "We heard a big boom last night around 8:40 p.m. ... It shook people’s homes and freaked a lot of people (us included) out!"

One area resident told officers that they believed a "flash bomb" had been thrown after noticing a dog barking during the incident.

Despite the reports, a search of the area by responding officers yielded no physical evidence of a blast, Miller said.

"At this time, we have received no further information and have no evidence of a crime," Miller said.

Miller said police also asked St. Charles Bend to notify them if any patients arrived at the facility with burns or injuries consistent with an explosion, but there had been none reported so far.

Police advised residents to contact them if they find any property damage or hear more loud noises.
