A briefcase filled with cash has been stolen from the Hamptons home Kourtney Kardashian and Scott Disick are renting this summer while they film the Keeping Up with the Kardashians spin-off Kourtney and Khloe Take the Hamptons.

Disick reported to the Southampton town police that $4,000 in cash was stolen from their home. The briefcase was located in their bedroom.

According to TMZ, there’s reason to believe the thief is someone in their inner circle, as this is the third Kardashian-related robbery and there were no signs of forced entry into the home.

Public information Officer Sgt. Susan Ralph told Newsday, “They've classified it as grand larceny 3rd degree, which is based on the amount of money. It's an ongoing investigation."

In March, $50,000 in cash was stolen from the couple from their Calabasas, Calif. home. The robbery was around the same time that $200,000 worth of valuables were stolen from Khloe Kardashian and her now estranged husband’s marital home.

It’s possible that the thief is someone working on the crew for E’s KUWTK.
