The sheriff’s office said it made the stop after authorities in neighboring Palm Beach County put out a “be on the lookout” alert. Photos included in the post showed an SUV stopped behind multiple law enforcement vehicles.

The post by the Martin County Sheriff’s Office indicated the suspect was apprehended near Palm City, Florida, about a 45-mile drive north of Trump’s golf course. Northbound lanes of I-95 were shut down, the sheriff’s office said.

Two law enforcement officials also told The Associated Press that an AK-style firearm was recovered near the golf course. Sources told CNN that Trump is believed to have been the target.

No additional details were immediately available.
