A police officer shot a man dead while chasing a group of gamblers at an illegal cockfighting den in the Mekong Delta province of Long An Sunday.
The incident happened when Lieutenant Le Quoc Thai and other officers from the Ben Luc District Police Department stormed an abandoned lot where around 20 men were gambling on cock fights.
After seeing the police officers, the gamblers tried to flee the scene.
The officers chased after the men, with Thai firing a warning shot in an attempt to stop them.
The gamblers continued to run, and Thai fired another shot.
The random shot hit 18-year-old Nguyen Phi Hoang, who was running in front of Thai, in the head.
Hoang was rushed to Cho Ray Hospital in Ho Chi Minh City but he succumbed to the injury soon after.
Thai told the police he tripped and fell while chasing after the gamblers and his gun went off by accident.
Investigations into the shooting are ongoing.
