The suspect in this week's stabbing spree in Incheon has cited frustration over his treatment at a hospital as the motive for his crime, police said Wednesday. The 59-year-old man gave the account to investigators during questioning, one day after he attacked random people at a shopping complex in the city west of Seoul, injuring eight, including one who remains unconscious. "I did not target any specific person, and I chose people who looked weaker than me, but I had no intention to kill," the suspect was quoted as saying during questioning at Incheon's Namdong Police Station. According to police, the man received treatment for athlete's foot at a local hospital but was unhappy that his symptoms did not improve and began to stage a one-man protest in front of the facility in August. The hospital reported him to the police for carrying a weapon during the protests, and he was booked last month before undergoing questioning last week. "I was unhappy with the hospital and unhappy that I was investigated by the police because the hospital reported me," he was quoted as telling investigators.
