Speaking to reporters as he left the police station, Sohn said, "I suppose the truth will eventually be revealed. I submitted all necessary evidence."
Sohn arrived at the police station at around 7:40 a.m. without answering questions from a throng of reporters. He was questioned as both a suspect in the convoluted saga and as a complainant against his alleged blackmailer.
Sohn Suk-hee, the chief and main anchor of cable channel JTBC, leaves a police station in Seoul on Sunday.
Earlier, freelance reporter Kim Woong (48) accused Sohn of assault and defamation. Kim claims that Sohn assaulted him in a bar in Sangam-dong in northwestern Seoul on Jan. 10, where they had met to discuss a job offer from Sohn to keep news quiet of a minor fender-bender that happened in 2017.
Some of the charges arise from Sohn's alleged attempt to use company money to keep Kim quiet, but the public has been much more interested in the question why Sohn was so desperate to hush up a minor bump with a tow truck in a dark parking lot at night.
Much of the speculation turns on a mystery woman who may or may not have been in Sohn's car at the time of the accident.
Conservative activists have sought to stoke the flames because they cannot forgive Sohn that JTBS discovered a vital piece of evidence early in the scandal that eventually brought down President Park Geun-hye.
Sohn accuses Kim of blackmailing him with the story to land a job at JTBC, which Sohn did in fact offer him. Kim in turn claims Sohn threatened him with unspecified legal consequences if he were to go public with the assault charge.
Police said the questioning took a long time due to the complicated charges and the he-said-she-said nature of the evidence. Kim will also be grilled shortly.
Sohn Suk-hee, the chief and main anchor of cable channel JTBC, was grilled for 19 hours at a police station in Seoul on Saturday over charges that he assaulted an alleged blackmailer.
