A major military and police search is under way in Colombia for the father of Liverpool forward Luis Diaz, with the authorities offering a £40,000 reward for information leading to his rescue.
More than 120 soldiers, plus police, searched northern Colombia for Luis Manuel Diaz on Sunday, amid reports armed men had taken him and his wife.
The player's mother, Cilenis Marulanda, was found in Barrancas on Saturday.
Diaz was absent from the Liverpool side which beat Nottingham Forest on Sunday.
The army said it had set up roadblocks and deployed two motorised platoons, unmanned aircraft, helicopters and a plane with radar in the search for his father.
The Colombian authorities have not provided details about the reported kidnapping, but local media said Diaz's mother and father were taken by armed men on motorcycles at a gas station in Barrancas, their home town, which is in La Guajira, the country's northern region .
Colombia President Gustavo Petro said "all the public forces have been deployed" to find Diaz's father.
Speaking on Sunday, the director of the National Police, General William Rene Salamanca, announced a reward of "up to 200m pesos" (about £40,000) for information.
Attorney General Francisco Barbosa said he had contacted Diaz twice to provide the 26-year-old with updates on the investigation.
Barbosa told Diaz that information has been obtained regarding the possibility that his father could be in Venezuela - a situation which, Barbosa said, would require intervention by President Petro.
Liverpool manager Jurgen Klopp dedicated Sunday's 3-0 Premier League victory over Forest to Diaz, saying they had won "for our brother"
Surrounded by his team-mates, Diogo Jota held up Diaz's number seven shirt after scoring Liverpool's first goal.
Liverpool said before the game that they were "aware of an ongoing situation" involving the family of Diaz and that his welfare "will continue to be our immediate priority".
Analysis

The number of kidnappings in Colombia has fallen massively since 2000, when more than 3,500 people were seized by guerrilla groups or criminal gangs. For the past years it has been in the low hundreds.
But this year that number has been on the rise, doubling from 77 in the first six months of 2022 to 161 in the same period in 2023, according to Colombia's ministry of defence. Almost all of the kidnappings are now carried out for ransom, the ministry says.
The border area with Venezuela, where Diaz's parents were reportedly seized, is among the worst hit as gangs which also engage in smuggling and people trafficking look to make quick money. They target well-off individuals and demand high sums for their release.
Unverified CCTV footage shared by Colombian media shows men on motorcycles following the car which Diaz's parents were travelling in, which appears to suggest that they had been singled out by the criminals.
Police have not said if the family has been approached with any ransom demands.
Specialised anti-kidnapping and anti-extortion units have been deployed to the area to free Luis Manuel Diaz.
