The disgraced composer Bahnus was arrested on Tuesday for selling a number of plagiarized songs to K-pop star Lee Hyo-ri, according to the Seoul Western District Prosecutors' Office.
Prosecutors said they took the step because he tainted the image of Korean pop music in the world and caused a huge amount of damage to the singer.
Lee's agency sued Bahnus in July for selling songs that he had basically copied for W29 million (US$1=W1,162). Seven songs on Lee's fourth album immediately drew accusations of plagiarism when the album was released this year. Lee admitted the charge in June, saying she had also been deceived, and has withdrawn from all singing engagements since then.
