Auto rickshaws slip easily past barbed-wire checkpoints at the world's biggest refugee camp. Their drivers are among the smallest players in a complex human trafficking network involving high-seas extortion gangs, corrupt police and drug lords.
Aboard the spluttering rickshaws are small groups of young men, women and children hoping to escape the misery of life with other members of their stateless Rohingya group who are crowded into shanties in Bangladesh.
Nineteen-year-old Enamul Hasan was aboard one of the rickshaws early this year, taken to the coast and then by small boat into a bigger fishing vessel anchored in the Bay of Bengal where he joined hundreds of other Rohingya hoping to reach Malaysia.
"I was told I'd get the opportunity to finish my studies and earn money to get my family out of poverty," Hasan told AFP, recounting the promises of the low-level smuggler in the camp who was his main contact for organizing the trip.
