A man in his 40s driving a Maserati in Seoul's Gangnam district caused a multi-vehicle collision while intoxicated, resulting in the death of a motorcycle rider and injuries to three others, including a bus passenger, a taxi driver, and a pedestrian. The suspect's blood alcohol concentration at the time of the accident was at a level that would result in license revocation. Due to concerns about potential flight risk, an arrest warrant was issued. Police are investigating the circumstances of the accident and plan to refer the case to the prosecution.
