In the aftermath of the attack, several high-profile South Korean politicians resigned or were suspended, and a commission was formed to assess the handling of the massacre by the police.

[3] However, Woo's heavy drinking and his behavior while intoxicated led to a demotion in Kungyu Village in Uiryeong County, South Gyeongsang Province.

[7] On the afternoon of April 26, 1982, Woo had an argument with his live-in girlfriend, Chun Mal-soon (전말순), after she had woken him by swatting a fly on his chest.

[citation needed] At about 7:30 p.m., Woo returned home, assaulted his girlfriend and smashed their furniture before making his way to the reservists' armory and gathering weapons, including two M2 carbines, two handguns, at least 180 rounds of ammunition, and seven hand grenades.

[4][6] Some reports stated that the other officers were at a meeting and did not notice Woo taking the weapons;[8] others mentioned that he had intimidated the guards to gain access.

When the owner of the house saw the armed policeman and asked what had happened, Woo explained that there was an alert as North Korean agents had been spotted.

[citation needed] Two hours later, police caught up with him, and as forces closed in, Woo strapped two grenades to his chest and detonated them, killing himself and three of his hostages.

[2][7] The Interior Minister of South Korea, Suh Chung-hwa, and the national police chief, A Eung-mo, offered to resign as a form of atonement for Woo's rampage.

[2] Suh Chung-hwa, whom president Chun Doo-hwan held responsible for the incident, resigned his commission on April 29, and Roh Tae-woo was appointed Interior Minister.

[14][10] A special parliamentary team was formed, consisting of 19 parliamentarians and led by Home Affairs Committee chairman Kim Chong-hoh, to investigate the massacre and its disastrous handling by the police.
