On January 7, Ryohei Yoshimitsu, of no known occupation, allegedly beat Tetsuo Takaoka in the victim’s residence in the Oyamakanaicho area of Itabashi Ward.
Upon his arrest on suspicion of inflicting bodily harm on Monday, Yoshimitsu admitted to the allegations, the Itabashi Police Station said.
Kayo married Yoshimitsu
Just before the incident, Yoshimitsu and Takaoka were drinking at the residence with the wife of Takaoka at the time, 45-year-old Kayo.
The assault took place after a dispute erupted. Afterward, Yoshimitsu and Kayo left the residence.
Two days later, Yoshimitsu returned to find Takaoka collapsed atop a futon with blood vomited from his mouth. After he called emergency services, Takaoka was confirmed dead at the scene.
At some point after the incident, Kayo married Yoshimitsu. On June 8, police arrested her on suspicion of negligence as a guardian resulting in death.
Police are now investigating whether the assault was connected to the death of Takaoka.
