At 2:30 p.m., the Aberdeen Police Department responded to reports of a loud noise and a small explosion near the early voting poll at Aberdeen Lake Park. Witnesses reported the incident occurred around 2:15 p.m. and initially believed a transformer had blown.
Investigators later found a civilian-style flash bang several feet from the roadway at US-1 and Lake Shore Drive, about 150 yards from the voting site.
Police say 30 witnesses were interviewed, with many saying the device appeared to have been thrown from a moving vehicle headed southbound on US-1. There were no suspect or vehicle descriptions provided.
"We heard a pop, one or two pops," said eyewitness Mike Freidel. "It was just so sudden, so fast."
Nobody was injured, but some people working at the early voting site were rattled.
"I saw it burst into three parts," said eyewitness Ray Daly. "Why would somebody do that?"
No property damage was reported.
In response, the Aberdeen Police Department has increased patrols and maintained a presence out of an abundance of caution.
"I think if there was a few more pops, we all would have been ducking," said Freidel.
Authorities believe this is an isolated incident with no additional threats reported.
"It's kind of concerning - trying to intimidate voters, election time - pretty scary," Daly said.
The investigation is ongoing, and evidence will be sent to the State Crime Lab for testing.
