Police have found texts in Cho Joo Bin's Telegram chatrooms during investigation that prove he ordered hidden cameras installed at Apink Bomi (27) and actress Shin Se Kyung (30)'s rooms.
According to Wikitree report, around 2:12pm on January 31, 2020, Cho Joo Bin, nicknamed "doctor" in the chatroom wrote, "There are many celebrity hidden cameras. A staff member got caught installing a hidden camera at Bomi's and Shin Se Kyung's rooms but it was us that paid for it. We hadn't done it before so that why we got caught. It's because we didn't how to do it right."
When a member of the chatroom asked, "What happened to the money?" Cho replied, "It was a late payment. We were only supposed to pay if the hidden camera was successful. It would've been around 3 million won (~$2,700)."
In September 2018, an outside staff member from "Pocha Without Borders" installed hidden camera equipment at Shin Se Kyung and Bomi's rooms while they were filming the show overseas. Shin Se Kyung found the hidden camera and reported it to authorities and the staff was sentenced to 1.5 years in prison and 3 years probation.
Police found further texts where Cho Joo Bin claimed he was the one behind actor Joo Jin Mo's galaxy hacking scandal exposed by Dispatch in January. Cho wrote, "Didn't you know that Baksa was the one that cracked Joo Jin Mo? We didn't hack his account, we logged in. Joo Jin mo is the one that did the media play about it first so I got curious and opened the messages. His katalks are dirty."
However, a police official stated, "there's no evidence that the Cho Joo Bin blackmailed Joo Jin Mo."
