CHICAGO (CBS) — Several cars were stolen from a rental car company parking lot Wednesday morning at O’Hare International Airport.

Police said the cars were stolen around 2:50 a.m. from the Hertz rental lot at O’Hare.

A Hertz employee said the thieves got away with between 8 and 10 cars. A co-worker tried to stop the thieves by blocking the exit with another car, but at least one of the thieves rammed it with a stolen vehicle, creating an opening for all the stolen cars to get out.

The Hertz employee said cars are stolen all the time from the lot, because it is a “Choose & Go” facility, so keys are left in the cars.

Hertz will contact police later, after confirming exactly which cars were stolen.
