On August 9, 2007, Atsushi Kameoka, a restaurant employee in Osaka, allegedly broke into the restaurant, located in the Kitazawa area, and held a knife to the male manager, then 38, while stealing 20,000 yen from a safe.
Kameoka, who has been charged with robbery, admits to the allegations.
With the statute of limitations for the Setagaya case set to expire next month, police re-opened the investigation. Police then arrested Kameoka after the results of a DNA re-analysis of material taken from a mask found near the scene of the robbery proved to be a match for him.
Last month, police accused Kameoka in a separate case that took place in the same area the following year.
