According to reports on April 4, the illegal drug investigation team of the Gyeonggi Provincial Police Office has received an arrest warrant against Hwang Hana, well-known as JYJ member Yoochun's ex-fiancée and as the granddaughter of 'Namyang Dairy's founder. 

Hwang Hana is currently facing allegations of using illegal drugs some time last year. Police have learned that she was recently admitted to a hospital in the Gyeonggi province, and plan to put the arrest warrant into action soon. 

The arrest warrant comes shortly after Hwang Hana refused to respond to the police's subpoena, and after the investigation team submitted two earlier requests for a search and seizure warrant which were denied, as well as one earlier arrest warrant request which was denied. 

Meanwhile, Hwang Hana also has a history illegal drug charges from back in 2011.
