A staff member of the Embassy of Mongolia in Korea was involved in a three-vehicle collision while driving under the influence earlier this month, police said Wednesday, with the incident only coming to light nearly two weeks later. Gangnam Police Station said an administrative employee, identified only by the initial “A” under Korean privacy rules, caused a three-vehicle crash on a major thoroughfare near Sinsa Station in southern Seoul on Dec. 12 while driving under the influence. Police released the details on Dec. 24. A, a Mongolian national, was driving alone at the time of the crash, police said. Officers at the scene were unable to make an on-the-spot arrest because the individual is covered by diplomatic immunity. After confirming the driver’s identity, police allowed A to return home. A breathalyzer test later showed the driver’s blood alcohol level exceeded the threshold for license revocation, police said. The drivers of the two vehicles struck by A’s car suffered minor injuries, according to authorities. No passengers were reported in any of the vehicles involved. Po
