An elaborate jewelry store heist in Cherry Hill, N.J., netted thieves more than $300,000 worth of precious stones, police reportedly said.

The theft was discovered Tuesday morning at Sam Zeitlin Jewelers on the 800 block of Cooper Landing Road, Detective Joe Vitarelli of Cherry Hill police told The Philadelphia Inquirer.

First, thieves broke into a Chinese restaurant that adjoins the jewelry shop by cutting a hole through the roof decking, the newspaper reports. They used a ladder to enter the Four Seasons restaurant from the roof, Vitarelli reportedly said. Inside the restaurant, the thieves broke through a wall shared with the jeweler. They located the Zeitlin safe, drilled a hole in it, and removed the contents.
