Ho Chi Minh City police have pressed murder charges against a 32-year-old man accused of committing an acid assault on seven people last November, including a woman who rejected his romantic advances.
The city's prosecution agency will consider ratifying the charges.
Though no one died in the attack, under Vietnamese laws acts clearly intended to kill are tantamount to murder, regardless of the attacker's success.
Nguyen Van Dung, a native to the Mekong Delta province of Ben Tre and employed at an automotive accessories store in HCMC's District 5, will also faces charges of aggravated battery.
Police say Dung developed affections for Hong Kim Huoi, 24, in 2008.
After being rejected, Dung often followed Huoi to her workplace and home. He also made threatening and insulting statements to her over the phone.
Police say he decided to attack her with acid after learning she planned to return to her hometown in Kien Giang Province, also in the Mekong Delta, to get engaged.
On November 3, 2013, he threw acid at her as she exited the TMT souvenir shop on Nguyen Van Cu Street with her three sisters.
Police say Dung chased Huoi into a neighboring lottery ticket shop to continue dousing her with acid. The shop owner Tang Thuy Ha, her daughter and niece were also injured in the incident.
Dung was subdued by bystanders at the scene when he attempted to escape on a motorbike.
All of his victims were rushed to hospital. The adults suffered severe burns.
Subsequent examinations found Huoi had sustained injuries to 44 percent of her body, Ha 55 percent and the others between 3 and 10 percent.
Investigators said Dung deliberately targeted Huoi’s neck and chest, an act considered a clear attempt on her life.
