Cermeno and some of his relatives had been seized on Monday night near the La Urbina area of the capital Caracas.

Cermeno, 44, was a WBA super bantamweight and featherweight champion in the 1990s. He retired in 2006 with a 45-7 record.
He won the super bantamweight title after defeating Puerto Rican Wilfredo Vazquez in 1995 and kept it until 1997.In 1998 he won the featherweight title and held on to it until a year later.
After he retired, he helped young sportsmen.
His murder comes after 29-year-old Monica Spear, a popular soap-opera actress and former Miss Venezuela, was killed early in January.
She and her British ex-husband Thomas Henry Berry, 39, were shot dead by robbers as they returned by car to the capital with their young daughter.
