CATASAUQUA, PENNSYLVANIA β€” An explosive device detonated near a polling location in Lehigh County on Tuesday morning during primary elections, though no injuries were reported and voting continued uninterrupted, officials said.

According to state police, around 9 a.m. an unidentified individual threw an “unknown explosive device” from a vehicle near the United Church of Christ polling location in Catasauqua, a suburb of Allentown, WFMZ reported.

“It was an isolated incident from everything we can determine,” said Lehigh County Executive Josh Siegel, adding that the county did not receive any threats and that only one polling place was impacted.

Investigation Underway

Siegel reported that one vehicle was partly destroyed by the explosive. While it initially appears that the polling place was not the target, the investigation remains ongoing and little information is currently available.

“It’s being treated very seriously,” Siegel said. “We’re not taking any chances.”

Local, state, and federal law enforcement agencies are investigating the incident. WFMZ reported that state police indicated there was no information suggesting the incident was related to the polling place.

Political Context

The polling location is part of Pennsylvania’s 7th Congressional District, where Democrats are holding a competitive primary to select a nominee to challenge Republican incumbent Ryan Mackenzie in the fall election. Political analysts view Mackenzie as one of the most vulnerable Republican representatives in the country.

Despite the explosive incident occurring near the polling site, election officials emphasized that voting proceeded normally and was not disrupted by the morning’s events.

Election Security Concerns

The incident highlights ongoing security concerns surrounding polling locations. According to the Brennan Center for Justice, there were at least 227 bomb threats against the November 2024 election, including several in Pennsylvania. Most of these threats were deemed noncredible, though incendiary devices were used in multiple attempts to set fire to ballot drop boxes during the run-up to that election.

Counties coordinate with state and federal officials well before Election Day to monitor such threats and have contingency plans in place to mitigate any potential disruptions to the voting process.

Sean Drasher, the Lebanon County election director, said he works with his county’s emergency preparedness department to plan for various scenarios that could impact Election Day operations, including bomb threats or active shooter situations.
