A string of mass shootings by officers in recent years may involve many factors, but they highlight the need for an improvement in mental health services, experts say, following the nursery massacre in Nong Bua Lam Phu's Na Klang district that left 36 people dead, mostly young children, and others injured.
The shocking incident took place on Oct 6, when a former police officer, 34, carried out a gun and knife attack, then killed himself. He had been arrested for drug use and fired from the force. Police believed he committed the crime under the influence of narcotics, but an autopsy found he did not take drugs within 72 hours prior the slaughter.
