The Federal Aviation Administration is investigating two instances of lasers being pointed at news helicopters Wednesday evening, including at NBC New York's Chopper 4. Chopper 4 was heading to downtown Brooklyn to cover the arrest of an alleged Greyhound bus thief when it was struck by a green laser, seen in Chopper 4 footage above. The helicopter remained over Prospect Heights as the pilot and Chopper 4 reporter Dennis Protsko attempted to pinpoint the source of the laser from 1,500 feet in the air.
