According to a report by Pattaya Today, Michael Gassar, 48, and his Thai girlfriend had bought jewellery and had some drinks before taking a motorbike taxi to an auto teller machine (ATM).
When the cash machine snatched his card and refused to dispense his card or any cash, Mr Gassar became angry and repeatedly kicked the machine.
The taxi driver tried to restrain the foreigner to no avail.
The Thai man reportedly called upon six friends who readily attacked Mr Gassar — beating him with a metal rod and a beer bottle. Neither the victim nor his girlfriend could identify the assailants.
The Maltese is in hospital recovering from his injuries.
