TAK - A man high on methamphetamine hacked his elderly father to death with a meat cleaver, police said on Monday.

Police said they responded to a call on Monday and found 65-year-old Kong Khampiro sufferng inside a house in Tak's Ban Tak district with deep wounds on his head, back and both arms. 

His attacker, Khamwan Khampiro, one of Kong's sons, was hiding in the house and was quickly apprehended.

He appeared to be disoriented and told investigators that he killed in self-defence because he saw his father was going to shoot him. 

Khamwan's mother, Nongkran Khampiro, 50,  said her son is a meth addict and often hallucinated under the drug, usually thinking that someone is trying to kill him. 

The mother said her son had attacked his father twice in the past.

Prior to the attack Khamwan was deluded, she said, believing that his own father was planning to shoot him. He then grabbed a meat cleaver from the kitchen and attacked him, repeatedly hacking at his father despite pleas to stop.

Neighbours took the victim to hospital where he succumbed to his wounds.
