"Over one lakh Bangladeshis who entered India with valid passports and visa are traceless as on date," Meghalaya'a Additional Director General of Police Kulbir Khrishna said while speaking at a seminar 'Changes in Security Perspective of Indo-Bangladesh' here.

He said the number of these missing Bangladeshis could be ascertained as they had valid documents. However, the total illegal migrants in India could be astounding, he said.

Pointing that there was evidence to show the involvement of HUJI, which has proximity to Bangladesh's intelligence agency DGFI and Pakistan's ISI, in a number of terror attacks in the country in the recent past, Khrisnan said the porous border has fomented the movement of insurgent elements and illegal migrants.
