The Sahastra Seema Bal (SSB) personnel nabbed a Chinese national in West Bengal while she was attempting to enter Bhutan.
The 52-year-old woman Ni Wai Lin was arrested on Thursday evening in Jaigaon, Alipurduar district, while she was trying to cross into Bhutan’s Phuntsoling town.
As per reports, she had a valid Chinese passport but her Indian tourist visa had expired.
Lin has been handed over to Intelligence Bureau (IB) for questioning.
The IB’s Counter-intelligence cell is interrogating her.
Lin’s arrest comes within a fortnight of BSF intercepting a Chinese national Han Junwe in Malda district while he was entering India from Bangladesh.
He confessed to procuring 1300 Indian SIM Cards which were used to perpetrate financial frauds.
But IB is exploring a ‘national security’ angle as Han’s network linked to financial frauds could also be used for paying off Chinese agents in India.
Both were found to have taken sharp high-resolution photographs of strategic areas like the Rachen La pass on the Sikkim-Bhutan border near Doklam, where Chinese military intrusions were resisted by the Indian army in 2017.
