Police used patrol cars as battering rams to stop a pickup truck that led officers on a chase Thursday that ended at Sky Harbor International Airport (search).

TV footage showed the truck driving along the airport grounds and then tearing through a fence, which remained wrapped around the truck as police stopped it. The reason for the chase wasn't immediately clear.

Sky Harbor officials released a statement saying there had been minor flight delays.

Car traffic at the airport was back to normal, the statement said.
