Bangladesh border guards spotted the makeshift raft overloaded with more than 50 passengers as it drifted toward the coastal village of Shah Porir Dwip village.
Local border guard commander S.M. Ariful Islam told AFP the 52 refugees tied plastic jerrycans together to float across the Naf River separating the two countries.
Islam said those fleeing ethnic violence in Myanmar were still desperate enough to make the dangerous crossing, with other daring escapes recorded in recent days.
