Police are seeking an arrest warrant for a man who trespassed into the Gwangju High Prosecutors' Office and attacked an employee with a weapon.

The Gwangju Dongbu Police Station said on Tuesday that it filed for a court warrant against the 48-year-old man on charges of special bodily injury. He was taken into temporary custody at the scene.

On Monday, the man allegedly trespassed into the prosecutors' office, threatening security in the lobby with a one-meter-long knife. He then managed to get up to the eighth floor, where he attacked the victim in his 50s.

While the suspect is reportedly exercising his right to remain silent, the police have so far confirmed that he has no connection to cases under investigation in Gwangju or the nearby South Jeolla area.

The police suspect the man, who lives in the southeastern South Gyeongsang Province, could have committed a hate crime. He reportedly claimed on his blog about three hours before the attack that people of the Jeolla region became judges, prosecutors and lawyers for revenge.

Investigators plan to further investigate the motive behind the crime to apply an attempted murder charge.
