The joint team of survey officials have been confronted several times in the past one week, by Bangladeshi people allegedly backed by the Bangladesh Rifles (BDR), official sources said.
In the wake of the frequent attacks, Bangladeshi survey officials have rushed back to Dhaka and are likely to report the matter to higher authorities there, they said.
BDR personnel, allegedly backed by armed Bangladeshis, illegally entered India and confronted the joint team of survey officials of Meghalaya and Bangladesh several times in the past one week.
There was no objection from Bangladeshi border guards when survey of disputed Lubachera (37 acre) and Baraibari (189 acre) areas � both under "adverse possession" of Bangladesh - was carried out.
BDR men are obstructing the survey at those stretches which are held by India like Muktapur, Lyngkhat and Pyrdiwah, the sources said, adding BDR men claimed before the survey officials that those land belong to Bangladesh and were not disputed.
The survey, which started on December 7, is expected to pave the way for settlement of the boundary dispute.
The exercise, which was mooted by the Joint Boundary Working Group during its meeting in New Delhi in November 2009, is being conducted by survey and land records officials of Bangladesh and Meghalaya.
In that meeting, it was decided that BDR and BSF would provide "outside security" to the officials conducting the survey.
The verification is to be conducted in 12 disputed patches bordering Meghalaya, stretches of which are under ''adverse possession'' of either countries.
According to official records, currently, there are 551.8 acres of Bangladeshi land under ''adverse possession'' of India (Assam and Meghalaya) while 226.81 acres of Indian land is under ''adverse possession'' of Bangladesh.
The areas under adverse possession were created when the two countries demarcated the international boundary in the mid-1960s.
