FARGO, N.D. (AP) — Authorities are investigating a second incident within about a month of an airplane pilot being harassed by a laser while approaching Fargo's airport.

Police tell KFGO radio a pilot reported a laser being aimed at the cockpit of a plane just south of Hector International Airport about 11 p.m. Monday.

It happened about the same time and in the same area where another such incident occurred June 9. Searches of the area have not turned up any suspects.

Lasers pose a safety risk to planes because they can temporarily blind pilots. Pointing a laser into the cockpit of a plane carries a maximum punishment of five years in prison and a $250,000 fine.
