LOS ANGELES (AP) – A Los Angeles man has pleaded guilty to pointing a laser at aircraft.

Federal prosecutors say 19-year-old Adam Gardenhire of North Hollywood pleaded guilty Monday to a federal offense. He faces up to five years in federal prison and a $250,000 fine.

Prosecutors say Gardenhire aimed a commercial-grade green laser at several aircraft in late March, including a Cessna private plane and a Pasadena police helicopter.

The Cessna pilot suffered temporary vision problems.
