Lawyer Kang Yong Seok and reporter Kim Se-ui that run YouTube Channel 'Garo Sero Research Institute (hereinafter 'Ga Se Yeon') are alleging that they know who installed the hidden camera on KBS 'Gag Concert' bathroom.
On the 2nd, Ga Se Yeon posted a photo of comedian Park Dae Sung (31) on their YouTube channel alleging that he was the suspect A being investigated by police. The Chosun Ilbo had reported earlier that the comedian that installed the hidden camera was selected for KBS public recruitment screening in July 2018 and is an active broadcaster.
Ga Se Yeon caused controversy after revealing Park Dae Sung's name as he became a KBS comedian in 2018 and has been active on many programming shows for 'Gag Concert.'
On April 29th, police discovered an illegal hidden camera device after receiving a report that a portable auxiliary battery shaped camera was found in a women's bathroom at the KBS Research Center after the cast appeared for final rehearsals.
After police began investigations suspect A voluntarily appeared at the police station in the early morning of the 1st. An official from KBS stated, "We cannot confirm the identity of the suspect."
In the meantime, comedian Park Dae Sung has since made his Instagram private.
