A woman was questioned Wednesday night by Osaka Prefectural Police in connection with an incident in which South Korean performer DJ Soda was allegedly groped by attendees at a music event in Sennan, Osaka Prefecture, investigative sources said on Thursday. Police had narrowed down suspects from security camera footage of the event.

The woman, a 21-year-old office worker from Mito, Ibaraki Prefecture, admitted to touching the performer: "(I was) so happy to see DJ Soda in front of me," she said, according to the investigative sources. She told police that she had touched DJ Soda on her breasts, hugged her and kissed her shoulders.

The organizer of the music event filed a criminal complaint Monday against two men and a woman, who were not named, alleging they indecently assaulted DJ Soda on Aug. 13. Two 20-year-old men surrendered to police later on Monday. They indicated they may have touched DJ Soda's breasts but did not grope her, according to police.

DJ Soda, who has over 5 million Instagram followers, took to social media to slam the unidentified individuals, accusing them of touching and grabbing her breasts when she descended the stage to interact with fans at the music festival.
