Film crew under suspicion following thefts at Khloé Kardashian and Kourtney Kardashian's homes

Khloé Kardashian and Kourtney Kardashian might have to look close to home when it comes to the recent thefts at their respective houses.

TMZ recently revealed that $250,000 worth of jewellery was stolen for Khloé and Lamar Odom's former marital home in Tarzana, and $50,000 cash taken from Kourtney's Calabasas mansion.

Now law enforcement sources have told the website that whoever stole the jewellery knew exactly what they were looking for — the thief or thieves only took the very expensive items, and left the rest behind. Adding weight to the theory it was an inside job, there was no sign of forced entry at either property.

Law enforcement sources have said that the Keeping Up With The Kardashian crew have come under suspicion, and are currently being questioned.

The theft at Khloé's mansion took place on 3 March, and was discovered when the reality star and her mum Kris Jenner were clearing out the complex in preparation for new owners Kaley Cuoco and Ryan Sweeting to move in.

Khloé filed for divorce from husband Lamar in December, and made the difficult decision to sell their home.

Newlyweds Kaley and Ryan have now settled into the 8,400-square foot Mediterranean-style complex in Tarzana — and this week showed off their new pad on Instagram.

"Home sweet home. Feel like I'm in friggin resort," tennis player Ryan wrote next to a picture of their spacious backyard pool surrounded by patio furniture.

Kaley, meanwhile, shared a photo of the couple's dogs running around outside and getting used to their new home. "Feelin' it out," the Big Bang Theory actress captioned a snap of the pets about to leap into the water.
