Brazil ? For the second time in four months, a judge has ordered a Brazilian to relinquish custody of a child to his U.S. father.

In this case, Hilma Aparecida Caldeira, a former member of Brazil’s national volleyball team and ex-Olympic contender, was ordered to return her 4-year-old son, Kelvin Caldeira Birotte, to his father, Kelvin Birotte, U.S. Embassy spokeswoman Orna Blum said Saturday.

Blum did not release the father’s age, hometown or state. Nor did she say when the judge made his decision or what the deadline was for handing over the child. She said she could not provide further details because of privacy issues.
