Los Angeles International Airport police are investigating a driver who drove through a fence and onto the airfield.

The intrusion forced a sudden closure of some of the runways Thursday evening, authorities said.

A statement by the Los Angeles Airport Police Division said the car went through a fence at a FedEx cargo facility, the Los Angeles Times reported.

The driver was detained and no injuries were reported, the statement said. An investigation is ongoing.

The airport�s two south runways were briefly closed and the two north runways continued operating normally, officials said on Twitter. The closed runways have since reopened.
