The pilot of a LAPD helicopter was forced to make an emergency landing after it was hit by a drone at a brush fire Tuesday.

"We were just informed shortly, about five minutes ago, that our airship was hit by a drone and had to make an emergency landing over at Van Nuys Airport. Everybody is OK, as far as we know. They are just going to do checks for damage and the safety of the crew," Capt. Brian Wendling told abc7.

"I know people are curious, but curiosity can cause danger."

Los Angeles Fire Chief Jaime Moore said power lines are believed to have sparked the eight-acre fire near the Encino Reservior. 

"What they found was about a 50x50 spot fire that was believed to have been caused by some power line that came down. Our firefighters immediately did an aggressive attack. We have our crews, hand crews, here as well, and they were mopping up that fire when, just up the hillside, another spot fire broke out because of the energized power line that hit the ground there," Moore said. 

Mayor Karen Bass said of the emergency landing: "I will say that it is completely unacceptable and illegal to fly drones like this. And we had that incident in previous fires as well. If you remember, in the Palisades, it hit one of the helicopters. So the message is -- this is unacceptable. If we find out who you are, you will be arrested, and you will be prosecuted. So any lookie-loos out there, this is very dangerous to everyone."
