LOS ANGELES (CNN) — A man apparently scaled a fence at Los Angeles International Airport Saturday, running up to a plane and causing a temporary shut down, according to police.

It was believed the man may have been under the influence of narcotics when he ran onto the 24-left runway at LAX — the most northern of the airport’s four — LAX police officer Rob Pedregon told CNN.

A pilot spotted the man and the passengers on his plane had to be transferred to another aircraft, Pedregon said.

“We had a temporary shutdown for the 24-left and right runways; and it was a minor shutdown,” he said.
