SEOUL, South Korea (AP) — A South Korean court found the former police chief of the country’s capital and two other officers not guilty over a botched response to a Halloween crowd crush that killed nearly 160 people in 2022.

The verdict by the Seoul Western District Court drew angry responses from grieving relatives and their advocates, who accused the court of refusing to hold high-level officials accountable for an incident that was largely blamed on a lack of disaster planning and an inadequate emergency response.

Kim Kwang-ho, former chief of the Seoul Metropolitan Police Agency, was the most senior police officer among more than 20 police and government officials indicted over the crush in Itaewon, a popular nightlife district in Seoul. Prosecutors had sought a five-year prison term for Kim.

An investigation led by the National Police Agency found that police and local officials failed to plan effective crowd control measures even though they expected more than 100,000 people to gather for Halloween events in Itaewon.

The investigators found that Seoul police assigned just 137 officers to Itaewon on the day of the crush. Police also ignored hotline calls placed by pedestrians who warned of swelling crowds before the surge turned deadly. Once people began getting crushed in an alley near Hamilton Hotel, police failed to establish control over the site and allow paramedics to reach the injured in time.

Some experts have called the crush a “manmade disaster” that could have been prevented with relatively simple steps like employing more police and public workers to monitor bottleneck points, enforcing one-way walking lanes, and blocking narrow pathways.

The Seoul court acquitted Kim of professional negligence, saying that prosecutors failed to prove that he had violated his duties or to establish a connection between his conduct and the high toll of deaths and injuries. The court also acquitted two lower-ranking police officers who faced similar charges.

The court stated that while Kim received status updates from various departments in his agency and the Yongsan police station about the situation in Itaewon before the crush on Oct. 29, 2022, this information would not have been sufficient for him to recognize the possibility of an incident of such magnitude.

The court also noted that Kim had instructed various police stations in Seoul, including Yongsan, to establish plans to maintain safety during Halloween celebrations.

“Based solely on evidence submitted by prosecutors, it's insufficient to conclude that the defendants’ professional negligence and its relationship to the occurrence or escalation of this incident are fully established beyond reasonable doubt," the court said in a statement. Relatives of the victims embraced and cried outside the court after the verdict was announced.

“This court just granted immunity to the police for whenever these kinds of incidents happen again!" one of them shouted. Others scuffled with security as they tried to approach Kim's car as he left the court.

Itaewon Disaster Bereaved Families, a group representing the victims, said the ruling was “dishonest” and “impossible to understand” and called for prosecutors to appeal.

“We strongly condemn that the main officials of the Seoul Metropolitan Police Agency, who ignored their duties for prevention, preparation and response despite anticipating that a large crowd would develop, and who have been denying their responsibility until now, are being given a free pass,” the group said.

The same court last month sentenced the former chief of Yongsan police station, Lee Im-jae, to three years in prison and convicted two of his colleagues of professional negligence resulting in death, citing their failure to properly prepare for the crowd and respond to the crush.

The court acquitted Park Hee-young, head of the Yongsan ward office, and three other ward officials, saying that they had no legal authority to control or break up crowds.

Lee and another Yongsan police official who received a one-year sentence appealed the ruling earlier this month. The other police official had received a suspended sentence.
