Lang Son provincial police have released official information on a murder investigation that has drawn significant public attention online. The case involves the killing of 35 year old Nguyen Xuan Dat and the arrest of 56 year old Doan Van Sang, a former deputy team leader of Market Management Team 4.
On the afternoon of 3 December, provincial police held a press briefing at their headquarters in Dong Kinh Ward to provide verified details and guide public understanding of the case, which had been widely discussed on social media.
Suspect Identified as Former Market Management Official
According to Colonel Vu Thanh Tung, Director of the Lang Son Police Department, investigators detected images and videos circulating online that appeared to show a violent crime. After reporting to the Ministry of Public Security, provincial police opened a special investigation with support from national level units.
Investigators confirmed that the victim was Nguyen Xuan Dat born in 1989 from Tien Hung Commune in Hung Yen Province. The suspect is Doan Van Sang born in 1968 from Tam Thanh Ward in Lang Son City and formerly a deputy team leader at Market Management Team 4.
Police said the two men first met around 2020 through social media. On 25 January 2025, Sang called Dat and asked him to come to the office of Market Management Team 4. At the building, Sang allegedly killed Dat. After the murder, Sang attempted to remove evidence and hide the body to avoid detection.
Arrest and Prosecution
On 28 November, investigators formally opened a murder case. On 29 November, police issued an arrest warrant and detained Sang on charges of murder under Article 123, Clause 1 of the 2015 Criminal Code. The provincial prosecutor’s office approved the arrest the same day.
Police also sealed off the former Market Management Team 4 headquarters for forensic examination.
Authorities say further investigation is underway to determine Sang’s full motives, whether others were involved and the extent of evidence tampering.
Police Urge Public Not to Spread Harmful Content
At the briefing, Colonel Tung urged media outlets and the public to avoid spreading unverified images or videos related to the case. He emphasized two main points:
-
Media organizations should actively counter false information and violent content being circulated online regarding the case, as such posts can mislead the public and destabilize social order.
-
Citizens should not share or comment on violent or sensitive footage. Unauthorized distribution of such material may result in legal penalties.
Colonel Tung also warned people to be cautious when joining social media groups that may contain illegal content and to promptly report any suspicious activity to authorities.
The investigation remains active as police continue to expand inquiries and collect evidence.
