The head of Peru's football federation was arrested on Thursday, just a few months after leading his country back to the World Cup for the first time in 36 years.
Prosecutors said Edwin Oviedo would be held initially for 15 days during an investigation of his alleged role in a criminal network that paid for several judges to attend the World Cup in Russia.
The 47-year-old businessman was taken into custody at his home in a wealthy section of Lima. Police were also seeking access to the football federation's offices.
The junkets for judges were allegedly aimed at buying support for Oviedo, who faces another investigation for allegedly ordering the killings of two sugar industry union leaders.
Oviedo has denied all accusations.
