A Colombian who confessed to sexually abusing nearly 300 children was sentenced to 60 years in prison.
Juan Carlos Sánchez Latorre committed the crimes in 2007-08, a court of the city of Barranquilla ruled.
Sánchez Latorre, in his thirties, used the pseudonym Big Bad Wolf to share images and videos of this abuse online.
He was arrested in Venezuela a year ago with a false identity card after five years of flight.
At the trial, Sánchez Latorre pled guilty to sexually abusing 276 boys and girls.
Prosecutors said they approached victims online and then met them in shopping malls, offering them money in exchange for sexual contact.
If they refused, they were often attacked, prosecutors said.
The authorities believe that Sánchez Latorre committed other crimes in Venezuela before being finally arrested in Maracaibo and extradited to Colombia in September 2018.
His neighbors said that they had never suspected that he could be a dangerous pedophile.
