A 49-year-old man was arrested on Monday afternoon after he fired shots into the Yokohama apartment of his former wife, police said.
The suspect was identified as Hiroyuki Hori, a former gang member, police said.
Hori's ex-wife, 42, and her two children aged 15 and 12, were not hurt in the incident which occurred at around 11:40 p.m. Sunday.
According to police, the woman said she was in the livingroom when she heard the intercom buzz. Immediately after that, the woman told police the front door had been partially opened and someone -- whom she could not identify -- fired a gun through the gap, TV Asahi reported. The bolt on the door prevented it from being opened further.
Police found a bullet hole in the hallway floor and another in the bedroom door.
The apartment is on the 10th floor of a condo in Minami Ward. Surveillance camera footage showed a man clad all in black acting suspiciously in the corridor just before the shooting.
Police arrested Hori in Hakone at around 1:30 p.m. Monday.
The woman and her children moved into the apartment about two weeks ago after Hori beat her. The woman told police that earlier Sunday night, she received a call from Hori saying he was coming over.© Japan Today
