In April of 2008, Atsushi Kameoka, a restaurant employee in Osaka, allegedly broke into the store, located in the Kitazawa area, and held a knife to a female employee while stealing 100,000 yen from a register.
Kameoka, who has been charged with robbery, has told police that he wishes to speak with a lawyer before commenting on the case.
With the statute of limitations for the Setagaya case set to expire in 10 months, police re-opened the investigation this year.
At the time of the incident, Kameoka did not have a criminal record. However, he was later apprehended in a separate case.
Police then arrested Kameoka after the results of a DNA analysis of material found on the knife used in the robbery proved to be a match for him.
