Police showed up to find Somchai and his wife Boonna (surname withheld) cowering outside the house. The couple said their son Vikorn, 34, went into a deranged state, possibly due to drugs.
He exploded when his demand for money was denied, and damaged everything in the house before attacking his father with a bat and threatening to murder his mother.
By the time police entered the house Vikorn had already escaped.
Somchai told the press that his son often goes into these fits, and he has called the authorities to catch him and have him committed to a mental institution. However, he said, they have failed to snare him so far.
