The Class II Singaraja Immigration Office identified the three by their initials, in line with Indonesian practice: AKG, 48, an Indian citizen; RN, 44, a Singaporean; and ST, 34, a Chinese national, Bali daily NusaBali reported.
AKG and RN were found running yoga sessions at a villa in Buleleng Regency, on Bali's northern coast, New York Post reported. Officers concluded the two were not only organizing the classes but teaching them.
ST was found at a factory in Karangasem Regency, in the east, installing production machinery and training the company's staff to operate it.
All three had entered on visitor permits. AKG and ST used visas on arrival. RN entered under the visa-free facility Indonesia extends to citizens of fellow ASEAN member states, Singapore among them.
Anak Agung Gde Kusuma Putra, who heads the Singaraja office, said neither permit covers work or any activity outside the purpose stated on entry.
