A 13-year-old Ayutthaya boy died yester- day after being badly beaten by his drug addict father. Somboon Lamphak, 36, the boy's grief stricken mother, later collected his body from Ayutthaya Hospital. The boy was rushed to the hospital on Tuesday with severe injuries. Ms Somboon said the boy's father,Tassanai Kaikluang, whom she divorced four years ago, beat her son over the course of three days. She said her ex-husband was addicted to methamphetamines and he told the boy to get 200 baht from his grandfather so that he could buy drugs. The boy returned with 120 baht prompting the father to beat him. Mr Tassanai was arrested yesterday.
