Philadelphia Police say they have busted a major auto theft operation.

Action News was in South Philadelphia as police seized more than a dozen cars and crews loaded them into a tractor-trailer.

The seizures followed a raid late Thursday night at a warehouse in the 800 block of East Oregon Avenue.

Sources say it was the culmination of a two-month-long investigation.

Officers arrested three people.

Investigators believe the vehicles, worth an estimated $500,000, were about to be shipped to Liberia.

More details were expected to be released on Friday.
