As clashes between pro-democracy demonstrators and pro-monarchy supporters erupted on Tuesday evening, he decided to hide the gun and ammunition near the fence of Wat Mai Thong Sen, on Thaharn Road in Dusit district of Bangkok. He feared it could cause problems for him.
He then went to wait near a military flat. When the situation calmed down, he went back to where he had hidden his gun.
Soldiers assigned to guard the area noticed him rummaging around for something. They moved in to see what he was doing, and uncovered the pistol and ammunition. They held the man and called police.
Mr Kasidit was being held at Tao Poon police station on charges of illegal possession of a firearm and ammunition, and carrying them in public without good reason.
