Tokyo police arrested a 46-year-old unemployed man Wednesday on suspicion of killing his 37-year-old ex-wife and their three children.

The suspect, Yusuke Goto, and his ex-wife, Fuyumi Takanami, had recently finalized their divorce but continued to live together in Tokyo’s Shinagawa Ward.

During voluntary questioning, Goto said that he was constantly berated by his ex-wife and told to leave the house, which led to his anger and sudden attack.
