The Ho Chi Minh City Prosecutors' Office has pressed criminal charges against two men for killing a senior Party official and seriously injuring two others, during a bizarre attack last September.
Nguyen Trong Nhan, 31, and Luong Hoai Sang, 21, have been charged with murder and robbery.
Both crimes are punishable by death under Vietnam's Penal Codes.
Investigators say that the two suspects have confessed to the crime which, they claim, stemmed from a work-related grudge.
On September 20, Nhan and Sang set out for the home of Bui Ngo Thi My, head of Phu Nhuan District's Natural Resources and Environment Agency.
The pair allegedly planned to force My to let Nhan's wife off the hook for public corruption.
Police say My was preparing to censure Nguyen Thi Thu Hien, 29, who supervised a group of land surveyors and housing inspectors, for accepting bribes.
Nhan worked at an online gaming company and Sang worked as a parking attendant at the Nguyen Tri Phuong Apartments in District 10 where Nhan lived.
Nhan prepared a taser, a knife and a pair of gloves and told Sang to accompany him and attack My if she refused to spare his wife.
On September 20, the men accosted My outside her home. She allowed them to enter but, once inside, she refused their demands.
Police say that the pair launched their attack - lashing out at the women with a nearby tennis racket and their fists.
My and her 24-year-old daughter were seriously injured. While the assault was in progress, Dang Thu Hong, 47, deputy chief of the Phu Nhuan District Party Unit, arrived for a lunch date.
Nhan allegedly stabbed Hong to death before militiamen stationed nearby heard My's cries for help. Around 100 police and militiamen were mobilized to the site where they discovered Nhan and Sang hiding in a pair of upstairs rooms.
Police say the pair confessed that they had planned to rob the household following their assault.
