Nepal deported 122 Chinese nationals in Kathmandu on Wednesday, officials said, being arrested on suspicion of the large-scale cyber fraud operation.
Last month, the police arrested nine households for raids, which were set up like hostels with large kitchens, beds and tables and chairs.
More than 700 mobile phones, 331 laptops and about 100 desktop computers were seized together with pen drives and SIM cards, acting on a tip-off from Chinese authorities.
The detention took place days after more than 340 Chinese nationals were arrested in an assault on unlicensed gaming companies in the Philippines.
Nearly 700 Chinese citizens were arrested in Malaysia in November when a major online investment scam operation was stopped by public authorities.
The Nepalese authorities said on Wednesday evening that the 114 men and eight women were flown to China and expelled for breach of immigration laws.
“They were found to have overstayed their visas or violated terms of their tourist visas,” immigration official Ram Chandra Tiwari told AFP.
