Colombia's Minister of the Interior Luis Fernando Velasco has announced Luis Diaz's father will soon be released.
The Liverpool star's mother and father were kidnapped at the end of last week. The mother was quickly released again, but the father has been held all week.
A branch of Colombia's National Liberation Army (ELN) had taken Luis Manuel Diaz last weekend.
Valasco has announced that the Colombian government has negotiated the release of Diaz's father, according to AFP.
It is not yet known when the release will take place.
