Lao authorities detained 41 people during three separate raids on rented homes in Vientiane Capital in early November.
Police investigated suspected cybercrime and online gambling operations, according to local media reports.
A Ministry of Public Security task force carried out the operations across Xaythany, Sisattanak, and Saysettha districts. Those detained included 16 Japanese nationals, 13 Bangladeshi nationals, 11 Thai nationals, and one Lao national.
Across the three properties, officers reportedly seized 87 mobile phones, 32 desktop computers, and four tablets.
In Xaythany district, the task force raided a rented house in Nalom village and detained 16 Japanese nationals, according to Laophattana News. Authorities suspected that the property served as a base for cybercrime.
Officers seized 55 mobile phones and four tablets from the house. Investigators were working to identify others who may have taken part in the suspected operation, including potential accomplices.
