A valuable camera and other prized possessions were among the belongings of the couple from Bahrain recovered when officers made an arrest at a workers' camp near Patong.
Security camera footage from the Indochine Resort and Villas, on the coast road north of Patong, allowed police to get their man quickly. He was named as Ismail Pormalee, 30.
The unnamed couple checked other belongings but found only the backpack and its contents were missing. They reported the theft at 9.30pm last night, as soon as they realised the bag was gone.
It was the second cat burglar capture within days and followed the arrest of a man who stole a mobile telephone from a villa at The Palmery in Kata.
