Read my comment and read the comment I was replying to by Robbkk. His comment was that Thai immigration dropped the ball. My reply was the UK dropped the ball allowing him to leave the country and also allowing passport renewal on an assumed reported stolen passport.
Quote from OP
Burrows had originally arrived in Phuket in 1997, living on the island under the name Peter Smith – the name in the passport he had allegedly stolen from one of his victim’s father. Somehow he was able to use this passport as ID to set up companies and even renewals for a new UK passport during his time in Thailand.
Many questions are being raised how a passport, assumed to have been reported missing by the real ‘Peter Smith’ in the UK, would be able to be used for such a long time without detection. During that time he would have completed numerous 90 day reports , visa renewals and UK passport renewals through the British Embassy inThailand.
