Police are hunting two men suspected of stealing a diamond ring worth ¥49 million from a jewelry store in Nagoya on Sunday evening, they said.

The police said Monday that the two men allegedly stole the ring from a De Beers jewelry store at the Matsuzakaya department store after asking a female worker to show them the ring among other items shortly before closing time at 8 p.m.

The store determined that the ring, which was the most expensive item in stock, was missing from the box only after the two had left, police said, adding security camera footage showed one of the two men reaching out for the box on a table as they sat opposite the staffer.

The pair mainly spoke English and occasionally Japanese, the police said. Both are in their 40s, were dressed in dark clothing, and were around 170 and 160 cm tall, the police said.

There were no other customers in the store at the time of the incident.
