LOS ANGELES (AP) – Authorities say a man walked into a Los Angeles emergency ward, stabbed a doctor and two nurses, then holed up for four hours before a SWAT team took him into custody. Los Angeles police say the man walked into Encino Hospital Medical Center shortly before 4 p.m. Friday, seeking treatment for anxiety, then stabbed the medical staff. Authorities say one victim underwent surgery and all three are in stable condition. Police say the man was confined to a room in the hospital as officers tried to talk to him. He was finally captured and taken to another hospital for treatment of self-inflicted injuries.
