Police have arrested a 22-year-old man in connection with the murder of a 75-year-old man found bound and dead in his Yokohama home last week.

The suspect, identified as Mazuki Takarada, a self-declared sole proprietor from the city of Inzai, Chiba Prefecture, was arrested on Saturday.

He has reportedly confessed to the charges against him. "There’s no mistake," he said during questioning. Takarada's arrest is the first in the connection with the Yokohama death. His case was transferred to prosecutors Sunday.
