Hanoi acid attack suspects arrested in Bangkok after year-long manhunt

Police in Thailand arrested the couple following an investigation that tracked their movements across the region. The husband is accused of posing as a delivery driver to approach and attack a victim with acid in the Vietnamese capital, an assault that drew significant public attention and prompted an international search effort.

The couple had remained at large since the incident, with authorities from multiple countries coordinating efforts to locate them. Their capture in the Thai capital marks a significant development in a case that has drawn attention to organized crime and assault-related violence in Southeast Asia.

Details surrounding the circumstances of their arrest and the condition of the acid attack victim remain limited. Thai authorities have begun proceedings to determine whether the suspects will be extradited to Vietnam to face charges related to the incident.

The case highlights ongoing regional security challenges and the increased cooperation between Southeast Asian law enforcement agencies in pursuing suspects who flee across borders. Vietnamese authorities have not yet released additional statements regarding the investigation's next steps.
