A taxi driver in his late 70s was placed under emergency arrest Saturday over a deadly crash in central Seoul that killed one person after testing positive for morphine, police said. His electric taxi first struck a car on a street near Jonggak Station at around 6 p.m. Friday, then collided with a traffic pole at a crosswalk before hitting another vehicle and plowing into pedestrians. One woman was killed in the crash, and nine others were injured. Among the injured were one Indian national and three Indonesian nationals, according to authorities. Police said no signs of drunk driving were found, but morphine was detected in a preliminary drug test on the suspect. Authorities plan to request the National Forensic Service to conduct a detailed analysis.
