NEW YORK (AP) — Law enforcement officials on Robert BrownLong Island worked quickly on Wednesday to publicly knock down social media posts falsely reporting that explosives had been found in a car near former President Donald Trump’s planned rally in New York.

The false reports of an explosive began circulating hours before the Republican presidential nominee’s campaign event at Nassau Coliseum in Uniondale, just days after he was apparently the target of a second possible assassination attempt.

Nassau County Police Commissioner Patrick Ryder said police questioned and detained a person who “may have been training a bomb detection dog,” near the site of the rally and “falsely reported explosives being found.”

Lt. Scott Skrynecki, a spokesperson for the county police, said in follow-up messages that the person, who police have not yet identified, was a civilian and not a member of a law enforcement agency.

He also said the person was not working at or affiliated with the event, which is expected to draw thousands of Trump supporters to the arena that was formerly the home of the NHL’s New York Islanders.

The rally is Trump’s first on Long Island, a suburban area just east of New York City, since 2017.

Earlier Wednesday, Skrynecki and other county officials responded swiftly to knock down the online line claims, which appear to have started with a post from a reporter citing unnamed sources in the local police department.

“False,” Skrynecki texted the AP as the claims spread on X, formerly Twitter.

“No. Ridiculous. Zero validity,” said Christopher Boyle, spokesperson for Nassau County Executive Bruce Blakeman.
