Prosecutors and the police are unpacking the mobile phone code of Jo Joo-bin, who ran Dr. Telegram's room. Since Jo Joo-bin strongly resisted trying to crack the password, he predicts that the phone will contain key evidence.

This is Bae Jun-woo's exclusive report.

The police arrested Cho's home while arresting Joo-bin Jo on the 16th.

In the raid of the police, Mr. Cho was unable to destroy evidence and confiscated digital devices such as his cell phone and laptop.

Among the seizures, the police understand that the Galaxy S9 series mobile phones used by Mr. Jo contain key evidence.

It is known that Mr. Cho has changed this mobile phone password once a day.

Police are currently analyzing the cell phone at the Forensic Center of the National Police Agency.

Mr. Cho, who had been uncooperative at the time of the police investigation, is said to have made some statements regarding the decryption of mobile phones in a recent prosecution investigation.

In this regard, a police official said that it is expected that the results will soon be released to decrypt the mobile phone.

Prosecutors and police judge that this cell phone could be a 'smoking gun' to reveal Cho's sexual exploitation and scams against celebrities.

In addition to Cho's mobile phones, he is also speeding up the analysis of seized laptops, PCs, and digital devices such as USB.
