A noncommissioned Air Force officer was sentenced to nine years of imprisonment Friday for sexually abusing a female colleague who later took her own life, according to a military court.

The master sergeant, surnamed Jang, was accused of groping the victim of the same rank inside a car in March. He also blackmailed her not to report the case to the authorities while sending threatening text messages.

The ruling by the General Military Court in Seoul came seven months after the victim took her own life in May. Prosecutors had sought a 15-year jail term for Jang in October.

The sexual abuse case sparked intense public fury, particularly as the Air Force is under criticism for failing to take appropriate steps to protect the victim while attempting to downplay the incident.

In June, Air Force Chief of Staff Lee Seong-yong stepped down to take responsibility. (Yonhap)
