Kim, Khloe and Kourtney Kardashian are fed up with several thefts that have taken place recently and won't film the next season of Keeping Up with the Kardashians unless the crook is caught.

The most recent theft occurred last month when $4,000 was stolen from Kourtney's home in the Hamptons. Before that, she had $50,000 taken from her California home and Khloe had $250,000 worth of jewelry taken from her house.

The family believes each theft was an inside job because there were no signs of forced entry and they're urging the show's producers to find the member of crew who's responsible. They're even urging producers to make the crew take a lie detector test. And until the thief or thieves are caught, the girls are refusing to shoot the next season of the reality show which is scheduled to begin in October.
