The roasted chickens had an unusual stuffing, US$150,000 worth of cocaine, according to Nigerian police.
A Nigerian mechanic who struggled in Brazil for more than six years had hoped the drugs would buy him a life of luxury in his native land, Nigerian authorities said Monday.
"This was like a retirement plan for him," said Mitchell Ofoyeju, spokesman for the National Drug Law Enforcement Agency.
The accused was arrested over the weekend at the airport in Lagos after he came in from Sao Paolo with 2.6 kilograms (5.7lb) of cocaine, Ofoyeju said. Photos from the agency showed egg-shaped packages wrapped in gold aluminum foil and tucked into the browned chickens.
The suspect, Vincent Chegini Chinweuwa, could not immediately be reached for comment as he remained in custody up to yesterday.
Nigeria is a major transit point for drugs coming from Latin America and going to Europe or the United States but recent security improvements are cutting into that dubious distinction.
