The Seoul Central District Court said the charges against Kim are disputable and that he presents little risk of fleeing given his current position.
The special prosecution questioned him twice this month, and filed for the arrest warrant on Wednesday on the charge of digital business obstruction.
He's accused of artificially jacking up likes on Internet news articles about DP, then main opposition, and its then-presidential front-runner Moon Jae-in in November 2016.
Druking argues he got "a nod" from the governor to carry out the scheme to influence public sentiment in favor of the party. He claims he showed him a demonstration of a computer program designed for such tasks.
Kim has denied the allegations. He admitted he had met Druking at his publishing company office but never saw any presentation about a computer program.
Special prosecutors have been digging into the case with strong suspicion that Druking and the governor worked together to sway public sentiment in the lead up to the June local elections. But they did not charge Kim on violation of the election law in Wednesday's warrant, apparently due to a lack of evidence.
The high-profile scandal has drawn heated media attention. Kim is known as a close aide to President Moon and is billed as a potential presidential candidate. (Yonhap)
