Police believe the thieves may be the same as robbed three expat houses in Bang Rong, a couple of kilometres away, two weeks ago (January 10).
Peter Tiehurst, 54, from Britain and Luksanawan Srisamut, 46, the owners of one of the Mission Heights homes, showed Thalang police a window at the back of the house where the burglars had broken a wire screen window in order to unlock the back door.
They then stole B30,000 cash with the wallet, passport, Visa card, ATM card and an iPhone 4.
Sawanee Hogbrow, 37, who lives with her British husband in another house in the complex, showed the police a side window the burglars had broken through a wire screen climb into the house.
In this instance an iPad mini, a wallet containing B1,000 cash and a purse were stolen.
The owners told the police that they have lived in the houses for many years and had never been robbed even when they left the houses unlocked.
Police believe that a gang of three are involved, traveling by motobike.
