Despite 12 hours negotiations between Thai Embassy staff and Japanese immigration police, Camronwit has not been allowed to board a flight out of Japan, after missing Flight TG640, which was scheduled to fly at 9.50pm Japan time and scheduled to land in Thailand on Monday at 5pm. 
	Camronwit reportedly arrived in Japan last Thursday on a personal trip. He reportedly told the Japanese police that he was unaware he had left his handgun and munitions in the carry-on luggage, while producing his police identity card and a document declaring his firearm. 
	He was quoted in news reports as saying he did not hide the contraband in his carry-on luggage on purpose but simply forgot to declare his possession of a firearm and follow the relevant protocol before boarding the flight. 
	Speaking over the telephone, he gave a different account, saying he did not know how his long-lost handgun was found in his carry-on luggage. &ldquo;I admit to my mistake but I did not intend to bring it to Japan or hide it from detection,&rdquo; he said.
