A man arrested in a recent random knife attack on passengers on a commuter train in Tokyo had difficulties in his personal relationships, including online dating rejections, according to investigative sources.
Yusuke Tsushima, 36, who had told investigators he wanted to kill "happy looking women," was sent to prosecutors Sunday for attempted murder after stabbing a female university student on board a rapid express Odakyu Electric Railway train on Friday.
The 20-year-old woman was seriously injured with multiple stab wounds to her back and chest, and nine other people — four women and five men — were also hurt. None of them knew the man.
