Actor Cha Joo-hyuk, who was a member of K-pop group Co-Ed, has been taken into police custody for illegal drug use.

The latest incident came less than two weeks after Cha was released from prison. He had served an 18-month sentence for illegal drug use and drunk driving.

According to police, Cha was taken into custody on Tuesday for disorderly conduct after causing a scene at an apartment in Seocho, Seoul.

During their investigation, police began to suspect that Cha took illegal drugs and he later admitted to the wrongdoing. A drug test also gave a positive result.

Police plan to ask the National Forensic Service to conduct a thorough examination, and to apply for an arrest warrant for Cha.

Cha debuted under the stage name Kangho as a member of the now-defunct K-pop group Co-Ed in 2010. He left the group after facing sexual assault allegations and changed his stage name to Cha Joo-hyuk to pursue acting.
