"The issue involves matters happening across the international border and I cannot confirm. I have sought for a report from the union home ministry and after I get information from New Delhi I can confirm this," he told reporters.
According to a Delhi report in a national daily, the HNLC 'c-in-c' Bobby Marwein was killed in a brawl with criminals in Dhaka this week.
Top police officials also said they were yet to confirm the report.
Significant, the CM, however, added, "Indo-Bangladesh relations in recent months have gained momentum with both sides taking steps to create a congenial atmosphere that could ultimately pave the way for broader bilateral, sub-regional and regional cooperation".
"We do not want that hostile elements of our country should be given shelter to perpetrate criminal activities against us from there (Bangladesh)."
Chief Minister Sangma will also accompany the PM to the neighbouring country, during which the CM is expected to raise issues relating to cross-border trade and movement of militants.
