A Colombian man has appeared in court accused of imprisoning his daughter and fathering eight children with her.
Arcebio Alvarez, 58, told a judge he was innocent, saying his accuser was not his biological daughter.
The eight children aged between one and 19, have been put under state protection.
Mr Alvarez was transported to jail under military guard to keep angry crowds at bay.
Alba Nidia Alvarez, the 35-year-old woman who claims to be his biological daughter, told police he had abused her since she was under the age of 10.
The accused told a different story when he went before a judge on Saturday afternoon in Tolima province.
"I adopted her," he said. "We agreed to have a romantic relationship because we really loved each other. But she was not my own child."
Alba Nidia's mother died when she was 5, leaving her under the care of Mr Alvarez, who has been branded "the monster of Mariquita" by the local press.
Elvira Forero, head of Colombia's child welfare agency, called the case "an intolerable crime."
Child welfare advocates have called for a sentence of life in prison should Alvarez be convicted, saying were are hundreds of thousands of child sexual abuse cases in Colombia not being prosecuted.
