Muyaddidi Dorloh, 27, of Narathiwat, and Sofian Arba, 25, of Yala, were caught separately on Tuesday evening, one in Phuket and the other in Satun.
They were wanted on arrest warrants issued by the Phuket provincial court for colluding in armed robbery and damaging property, Phuket police chief Pol Maj Gen Rungroj Thakornpunyasi said on Wednesday.
The suspects allegedly broke into a house in tambon Rassada of Phuket on Thursday evening.
The intruders tied up German national Wilhelm Christian Schrei, 70, with black tape and used a basket to cover his head.
They were allegedly armed with a machete and a 30-centimetre knife, and inflicted a long cut on his arm.
When the victim’s Thai wife arrived home, the intruders also detained her. They reportedly robbed the couple of 2,000 baht cash and took their two ATM cards and the PIN codes.
During interrogation, the suspects allegedly confessed and said they were jobless and needed money. They said they were able to withdraw only 3,000 baht.
Police said the victims had quickly transferred money to another account after the robbery.
The duo were handed over to police at Muang Phuket police station for legal action.
