Bahraich, Oct. 23 -- The Sashastra Seema Bal (SSB) detained three Sri Lankan nationals and a woman from Tamil Nadu near the Rajjanwa checkpost along the Nepal border, late on Wednesday night after they were found enquiring about a route to Nepal. According to preliminary information, the four had arrived in an auto-rickshaw and were attempting to cross into Nepal through a forest-adjacent border route.

The detained individuals were identified as Ajith Kumar (39), Kaushalya (38) and Prabhap (38), all residents of Jaffna, Sri Lanka, and Dharma Sudhakar (35), a resident of Tamil Nadu. Police are questioning the four and circle officer Amit Kumar confirmed that the three Sri Lankan nationals possessed passports with expired visas....
