Two men were arrested near Boston’s Logan Airport for operating a drone dangerously close to airspace, amid rising concerns over drone swarms in New Jersey and Connecticut.

Two men suspected of operating a drone “dangerously close” to Boston’s Logan International Airport were arrested Saturday night and charged with trespassing, authorities said.

The arrests took place on one of the Boston Harbor islands amid ongoing concerns over drone sightings in airspace across New Jersey and Connecticut, which have alarmed residents and prompted calls for federal drone detection equipment. Some have even suggested shooting down the mysterious aerial swarms.

According to the Boston Globe, Robert Duffy, 42, and Jeremy Folcik, 32, were taken into custody by harbor patrol officers just before 10:30 p.m. at a decommissioned health campus. Police said they were investigating a “hazardous drone operation” near the airport when the arrests occurred.

A third suspect, believed to have fled the island on a small boat, is currently being sought by police. Authorities reported finding a drone in Duffy’s backpack, and the two arrested men are set to be arraigned on Monday.

The investigation began about six hours earlier when a Boston police officer using surveillance technology detected an “unmanned aircraft system” operating near Logan Airport. Police were able to pinpoint the drone’s location, altitude, flight history, and the operators’ position on Long Island in Boston Harbor.

“Even small drones pose significant risks, including the potential for catastrophic damage to airplanes and helicopters,” police stated. “Near-collisions can cause pilots to veer off course, putting lives and property at risk.”

Boston police coordinated with multiple agencies in response to the incident, including the Department of Homeland Security, Massachusetts State Police, the Joint Terrorism Task Force, the Federal Communications Commission, and Logan Airport’s air traffic control.

The situation highlights increasing concerns about drone activity and its implications for public safety. US Senate Majority Leader Chuck Schumer on Sunday joined other officials calling for federal-level drone detection technology to address the problem.

Meanwhile, Florida Congressman Mike Waltz, who has been appointed national security adviser for the second Donald Trump presidency, commented on the broader issue of unexplained drone sightings. Speaking to CBS’s Face the Nation, Waltz noted that these incidents reveal gaps between federal agencies and local law enforcement.

“Americans are finding it hard to believe we can’t figure out where these are coming from,” Waltz said.
