The national anger over the spread of sexual exploitation of women, including minors, through the Internet messenger, Telegram, is increasing. More than 2.3 million people participated in the Blue House petition to reveal the identity of the suspect one hour before. SBS determined that this was a cruel sexual offense against adolescents and a serious crime that left irreversible scars on victims.

So we decided to release the faces and names of the arrested suspects, along with our exclusive coverage, in order to prevent further damage and to assist in the investigation by finding crimes that have not yet been revealed. This is Jo Joo-bin, 25, who has created and operated a chat room called Dr. Bang in Telegram. Then, I will tell you who Jo Joo-bin, who first committed a terrible crime.

Only 74 victims have been identified so far, including 16 minors.

Jo Ju-bin, 25, who exploited them sexually and cruelly, graduated from college in 2018.

I went to the school where Mr. Cho graduated and heard about how his school life was.

Cho majored in information and communication, but loved to write, so he won first place in the after-school reading competition and worked as an editor at Hakbosa. I have also written several columns in the academic journal, but I have moved my sentiments from school life to emotional writing.

I got many scholarships because my grade point average of 3 semesters exceeded 4.0, so my grades were good.

In terms of grades and on-campus activities, motives and juniors say they deserved a good student rating, but their relationship was not smooth. [Hakbosa colleague: I wrote articles at my own discretion and had some troubles with my professor. There was trouble with secretary, too. Something was troubled.]

However, it is the message of the classmates that Mr. Cho has never deviated from school due to sexual problems.

[Academic assistant: I think it was a quiet child that I could see everywhere.]

The police have been aware of the fact that Mr. Cho began the crime since 2018, shortly after graduation.

Cho, who first made a false advertisement to sell firearms or drugs on the telegram and stealed money, started making a sexual exploitation by making a 'doctor's room' on the telegram last September.

When Gatgat, the operator of Room n, the starting point of the sexual exploitation operation room, withered, he made money by using more provocative sexual exploitation.

The police plan to hold the 'Disclosure of Personal Information Disclosure Committee' tomorrow (24th) and decide whether to disclose Mr. Cho's personal information.

[Hakbosa colleague: First of all, I was horrified that the doctor was a person I knew. .]
