Police have launched an investigation after abusive graffiti was found on a banner of Kim Sang-wook, a member of the People's Power who even staged a "one-man protest" in favor of the vote to impeach Yoon Suk Yeol's president.

According to the Ulsan National Police Agency and Kim Sang-wook's office on the 17th, a police officer on patrol found a banner installed on the industrial tower rotary transportation island in Nam-gu, Ulsan, with swear words in red letters.

The banner was installed in front of Kim's district office on the afternoon of the 14th, the day of the impeachment of President Yoon. The banner reads, "We deeply apologize for the martial law disaster."

Police are looking for the culprit who scribbled through the analysis of CCTV.

Meanwhile, Rep. Kim publicly expressed his support for the impeachment and held a one-man protest in front of the National Assembly's main office urging the ruling party to approve the impeachment.

Since then, he has confessed that he is threatening to kill and being bullied by his colleagues.

It is known that he has requested personal protection from the police after a series of threatening calls to his family.
