An argument over an insult made on an on-line English forum aimed at helping students improve their English in Vietnam, led to an offline confrontation, and ultimately murder in Vietnam. Police are now searching for Nguyen Van Xuan an English student at Hanoi Open University who confronted Nguyen Minh Ngoc for calling his girlfriend 'crazy' on the forum. When the victim refused to apologize, he took a knife out of his bag and stabbed him. The forum has been temporarily disabled. This is yet another incident in a series of such cases where on-line remarks and behaviors have resulted in severe drastic offline consequences.
