SAN BERNARDINO, Calif.—Authorities have arrested a man suspected of threatening to shoot down the next sheriff's helicopter that flew over his Joshua Tree home.

The San Bernardino County Sheriff's department said Thursday that 55-year-old Gene Richard Lombardo called in the threat to authorities on Dec. 14, prompting deputies to alter their flight course around his house.

Authorities said deputies raided Lombardo's home on Wednesday and found multiple firearms, ammunition and an indoor marijuana growing operation.

Lombardo was booked into jail on suspicion of obstructing an officer and cultivating marijuana. Bail was set at $150,000.
