South African authorities intercepted 50 eggs believed to be from endangered parrots at Johannesburg's main airport last Thursday, with reports that some of the eggs have hatched since.
A 50-year-old Thai national was arrested on suspicion of attempting to smuggle the eggs in a homemade incubator bag carried as hand luggage, according to the Department of Forestry, Fisheries and the Environment.
The eggs are being treated at the National Zoological Garden in Pretoria, where they are under intensive care as officials investigate the case.
If convicted, the suspect could face a fine of up to 10 million rand, a prison term of up to 10 years, or both, the department said.
Initial investigations indicate the eggs belong to a parrot species protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The department said the arrest followed a joint operation involving the Green Scorpions and police, and noted that a 23-year-old Thai citizen was also arrested in July at OR Tambo International Airport over an alleged attempt to smuggle 418 parrot eggs.
