SEATTLE – Federal authorities say a Port Angeles man is under arrest for pointing a laser at a U.S. Coast Guard helicopter.

U.S. Attorney Brian Moran says Randall Muck was arrested Monday after being indicted by a grand jury last week on charges of aiming a laser pointer at an aircraft and lying to government agents.

A Dolphin helicopter aircrew was making a final approach to Air Station Port Angeles, at 8:23 PM on Monday Sept. 26, 2016 when, according to the indictment, Muck aimed the laser at the aircraft, which can cause temporary loss of vision for the crew.

They safely landed and were checked out by the duty corpsman who medically cleared the crew to resume duty.

Muck later made false statements to FBI agents who investigated the laser incident.

The two charges carry five-year prison sentences and a $250,000 fine.

It was not immediately known whether Muck has a lawyer. No lawyer was listed on his federal court case.
