Investigators are seeking to question the wife of a police senior superintendent suspected of collusive ties with K-pop stars mired in the Burning Sun scandal.
 
The Seoul Metropolitan Police Agency said on Tuesday that it is arranging to summon the wife, who is also a police officer one rank below her husband. 

Police have secured testimony from rock band "FT Island" member Choi Jong-hoon that he had gotten the wife tickets to a K-pop concert in Malaysia, where she is currently dispatched. 

Identified by his last name Yoon, the husband was referred to as a "police chief" in Big Bang member Seungri's controversial KakaoTalk group chat with his friends. 

The police requested the court to issue a warrant to obtain Yoon's bank transactions and telecommunication records and will request a travel ban for him later on Tuesday.
