The gunman behind a massacre in Thailand that killed at least 36 people had a history of drug offences and violence, police said on Thursday.
Panya Khamrab, 34, stormed a nursery in Nong Bua Lamphu, northern Thailand, and killed 24 children, as young as two years old, among 38 killed overall with 18 injured.
The perpetrator then drove home to turn the gun on himself, his wife and his child.
