|Some of those arrested by Kenyan security forces|
Police say they picked up the men late Friday from two houses in an upscale area of the coastal city of Mombasa after an anonymous tip.
They say officers found very little in the houses, only mattresses, small amounts of food and computers.
A Kenyan caretaker of the houses also was arrested. The Kenyan told police that all the Bangladeshis were crew members of two vessels, sailing from Turkey. However, police say the men did not have seafarers' identification documents.
Bangladesh's foreign ministry says it is trying to get details about the arrests through its embassy in Nairobi. It says the suspects may be migrant workers who went to Kenya in search of jobs.
