Three bags of jewelry items worth some 50 million yen were apparently stolen Wednesday from a van used by a jewelry store employee while it was parked on a street in Tokyo's Taito Ward, police said.

The 30-year-old employee from a jewelry wholesaler in Kofu, Yamanashi Prefecture, found the black bags gone from the van's back and the driver's seat window smashed when he returned from a restaurant where he had been eating, police said.

They said they found two of the three tracking devices installed in the bags in Taito Ward and neighboring Bunkyo Ward, but that the bags and jewelry were not found.

The other tracking device failed to send a signal and was also probably removed from the bag, police said. The employee was on his way to a jewelry shop in Taito Ward to sell the jewelry, which included necklaces and rings.
