Police are reportedly considering compulsory measures against YouTuber Kim Se-ui, head of the controversial Garosero Research Institute, after he failed to respond to multiple summons related to high-profile lawsuits filed by internet personality Tzuyang and actor Kim Soo-hyun.

According to authorities, Kim has twice postponed his appearance for questioning in connection with ongoing investigations.
The Seoul Gangnam Police Station had scheduled interviews with Kim after both complainants completed their own sessions with investigators.
However, police confirmed that Kim cited "lack of time due to the presidential election" as the reason for not appearing.
Tzuyang, who filed a criminal complaint in February, accuses Kim of coercion, extortion, defamation under the Information and Communications Network Act, and violating the Stalking Punishment Act.
While the case was initially dismissed due to insufficient evidence, a supplementary investigation was launched following her legal team's objection.
"Even after the presidential election, we inquired with the responsible police officer, but we were told that the suspect's investigation has still not taken place," said Kim Tae-yeon, an attorney representing Tzuyang, in a statement to SBS Entertainment News.
"The police mentioned they are considering visiting [Kim's] residence to directly coordinate the schedule."
Meanwhile, Kim Soo-hyun also filed a lawsuit in April, accusing Kim Se-ui of defamation and violating the Special Act on the Punishment of Sexual Violence Crimes for allegedly distributing unauthorized video content.
A representative from Kim's side confirmed he had already completed his interview with investigators.
"It's difficult to provide specific details, but we understand that the suspect has postponed the investigation schedule twice," said the representative. "We are unaware of the reasons."
As criticism mounts over Kim's lack of cooperation, a police official said authorities may escalate the situation.
"If the suspect continues to fail to attend without justifiable reasons despite active summons requests, we cannot rule out the possibility of switching to compulsory measures, such as issuing an arrest warrant," the official said.
Kim Se-ui, known for his involvement in politically charged YouTube broadcasts, has yet to publicly address the possibility of legal action stemming from the ongoing investigations.
The developments come amid increased scrutiny of online platforms and calls for legislation addressing digital defamation and harassment.
