Police in Niigata said Sunday that a male patient in a psychiatric ward in a hospital killed another male patient on Saturday night.
According to police, the 50-year-old suspect, who hasn't been identified, was admitted to the two-bed ward at Nittsu Shinai hospital earlier Saturday, NTV reported.
Police said that at around 7 p.m., the suspect strangled 69-year-old Satoru Yoshizawa who was in the other bed. Neither patient had restraints, police said.
A male orderly discovered Yoshizawa's lifeless body on the floor when he made his rounds at 8 p.m., police said.
The suspect was quoted by police as saying Yoshizawa's coughing annoyed him and they argued about it. When Yoshizawa wouldn't stop coughing, the suspect said he strangled him with his hands, police said.© Japan Today
