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.
