Police have arrested a 39-year-old man from Hanyu, Saitama Prefecture, on charges of attempted murder in relation to a knife attack in which three Cambodians were injured.
Saitama Prefectural Police said Sunday that Hideaki Nakayama had entered a different apartment in the same building where he lives through an unlocked window at around 9 p.m. a day earlier and attacked a 32-year-old man, a 29-year-old man and a 34-year-old woman. The three suffered minor injuries to their chests and stomachs, authorities said.
There were seven people in the room at the time of the incident, and Nakayama had several knives, police said.
Nakayama has admitted to the charge, according to investigators.
"I went into the room because I wanted to kill a person," he reportedly told investigators.
