Tokyo police arrested a 47-year-old man on Saturday on suspicion of killing a 29-year-old woman in an apartment in Tokyo's Roppongi district in 2018. The suspect, Nobuaki Takahashi, whose address and occupation are unknown, told the police that he had nothing to say about the case. The suspect left for Malaysia the day after the 2018 murder.

Takahashi is suspected of killing the woman by repeatedly striking her on the head with a blunt object at his apartment in Roppongi on either Oct. 11 or 12, 2018.
