Military prosecutors on Wednesday sought an arrest warrant for an air force non-commissioned officer on charges of sexually harassing a female colleague.

The defence ministry said the warrant followed mounting criticism that the military’s mishandling of the case led to the victim taking her own life.

Investigators also took the suspect, identified as Master Sergeant Jang, into custody.

He was suspected of sexually harassing the victim of the same rank inside a car on their way back to the base in the western city of Seosan after a private gathering in March.

A military court was to hold a hearing to decide whether to issue the warrant, the ministry said.

The military came under intense criticism following revelations that the victim took her own life, and her family members claimed her superiors tried to persuade her to reach a settlement with the alleged perpetrator without taking due protective measures.

Earlier in the day, Defence Minister, Suh Wook, pledged a transparent and thorough investigation when he met with the bereaved family members at a military hospital in Seongnam, south of Seoul, where the body of the female master sergeant was laid.

“We will thoroughly look into the case so that there is no room left for any doubts,’’ Mr Suh told the parents of the late master sergeant, promising a transparent investigation, according to pool reports.

Following an hour-long closed-door meeting with the minister, the mother of the late victim passed out after sobbing in front of her daughter’s portrait and was transferred to a hospital.

On Tuesday, Mr Suh ordered the air force to hand over the case to the defence ministry. The investigation team will also look into whether the military appropriately handled the case when it was first reported.

Starting from June 3, the ministry will also run a two-week special reporting period for sexual harassment cases in the military to check if there were any other sexual violence cases in barracks.

According to the ministry, service members who suffered or witnessed sexual abuse can report it via a phone call or email.

“Through this special reporting period, the defence ministry will make utmost efforts to protect victims who haven’t been able to report their sufferings,’’ the ministry said in a statement.

Meanwhile, the air force is also looking into a case where a technical sergeant in the central city of Chungju allegedly broke into the quarters of his female colleagues and illegally took photos of their bodies and underclothes.

At least six female service members were believed to have been victimised between 2020 and May 2021, but the number could grow further as he is suspected of committing such acts also against civilians.
