The parents of a man arrested for allegedly killing an elderly woman in Machida, Tokyo, have expressed wishes for their son to atone for his crime.

"We are sorry that our son took the life of an innocent person," the parents of the suspect, Kota Kuwano, 40, said on Wednesday. They said: "Why did he make the wrong choice? We want him to recognize what he did and pay for his crime. "

On Thursday, Tokyo's Metropolitan Police Department sent Kuwano to public prosecutors for alleged murder and violation of the swords and firearms control law.
