The 23-year-old, often known as Nichkhun, had a minor collision with a motorcycle at around 2:45 a.m. in southern Seoul’s upscale Gangnam area, the Gangnam Police Station said. His blood alcohol concentration, tested at the scene, was 0.056 percent, a level that could lead to the suspension of his driver’s license, the police said. His agency JYP Entertainment released a statement and apologized for the “carelessness” of the star’s actions. JYP said it will faithfully cooperate with the police for further investigation. Nichkhun sings and raps in the six-member boy band, which debuted on the K-pop scene in 2008.
