Jo Joo-bin, the operator of the doctor's room who spread the sexual exploitation video, was examined for the first time today (26th). The prosecution has decided to disclose the relevant investigations in the future for the right to know the people, while the police are chasing another man in his 20s who sexually exploited minors like Jo Joo-bin.

In December 2018, Ms. Lee was offered a sexual intercourse with a teenage woman from Mr. A, whom he found on Twitter.

Mr. A referred to the so-called 'slave' and sent the woman to Lee, who took the woman to the motel and raped her, filmed it and sent it to a group chat room with Mr. A and other men.

Another man, Kim Mo, was asked to make a video of sexual exploitation of a teenage woman in March of last year when he learned on Twitter, but was convicted last month.

Both men trampled the minor sexually, but they were only sentenced to three years in prison.

Mr. A's way of making minors into 'slave' and manipulating them to sexually exploit them is similar to that of the nth room Gatgat or Dr. Jo Joo-bin.

The SBS coverage confirmed that the police recently identified Mr. A's identity and began pursuing it.

Mr. A hacked Twitter and produced a video of sexual exploitation after threatening a teenage woman, and is also accused of distributing the video if not followed.

Police are narrowing the siege with the possibility that Mr. A will be one of the key suspects in Room n, the beginning of the Telegram Sex Exploitation Room.
