Liverpool star Luis Diaz's family have demanded the kidnappers holding his father hostage offer proof he is alive as concern about their failure to release him grows.
The left-wing ELN insurgent group so far failed to make good on its promise to free Luis Manuel Diaz despite saying at the end of last week it was working on liberating him as soon as possible.
It went on to accuse the Colombian government of hindering its efforts by maintaining a high military and police presence in the Perija Mountains on Colombia's border with Venezuela where father-of-four Luis Manuel is thought to be held.
