A Los Angeles man, believed to be under the influence of drugs, was arrested Saturday night at Los Angeles International Airport (LAX) after being seen on the runway.

The suspect had grabbed the landing gear extinguisher and set it off, which set off the cockpit alarm, Pedregon said.

"When asked why he did it, he told officers he was trying to fly back to Downey", Pedregon said. A police dog bit Hernandez before being captured, reported KNBC, an NBC affiliate in Los Angeles.

Pedregon said Hernandez will be booked on a trespassing charge and may face other charges.

According to Pedregon Hernandez was 'under the influence of some kind of narcotic or had mental illness.' He was taken to the hospital to be looked at.

The Southwest jet, heading to Sacramento, had been preparing for takeoff when Hernandez approached the wheel well.

Officials reportedly evacuated passengers from the damaged plane and onto another flight that left for Sacramento within an hour of the incident.

It wasn't immediately known how or why the man made it into the airport and onto the runway.
