SEOUL – A Yongsan Police Station officer was found dead Friday while under investigation in connection with the October 29 Halloween tragedy in Seoul's Itaewon neighborhood.

The 55-year-old intelligence officer, surnamed Jeong, was found dead at 12:45 p.m. at his home in northern Seoul by a family member.

The Yongsan Police Station, along with the fire station and the ward office in the district, has been under an investigation over suspicions they failed to promptly respond to the crowd crush that killed at least 156 people.

Jeong was investigated on suspicion that he allegedly ordered the deletion of an internal intelligence report giving prior warnings of a possible safety accident during the Halloween period in a suspected attempt to cover up inaction.

Charges raised against him included abuse of authority, destruction of evidence, and professional negligence resulting in death.

Jeong was reported to have sent mobile messages suggesting suicide to some colleagues the previous day.

Police are looking into the circumstances of his death. (Yonhap)
