Conflicts during a card game caused a man to damage the brain of a five-year-old while trying to chop his mother in southern Vietnam on Monday.
Investigation found Nguyen Thanh Binh, 27, had brought three armed men to the house of Tran Thi Mong Ngoc after the two argued over a card game earlier in the day, news website VnExpress reported.
Ngoc took her son and fled, but Binh managed to cut the boy's head with a falchion.
The men continued destroying Ngoc's house and threatened other people for about 10 minutes, before the boy was rushed to the hospital.
Binh handed himself over to the police.
The boy was saved after a three-hour operation to remove a part of his damaged brain.
