A female commander in the Revolutionary Armed Forces of Colombia, or Farc, has surrendered to police.
Nelly Avila Moreno, also known as "Karina", handed herself over to the Colombian authorities in Antioquia province, the Defense ministry said.
She was "nearly dying of hunger" when she and another guerrilla handed themselves in, Colombian Defence Minister Juan Manuel Santos said.
Moreno, who operated in the country’s mountainous, north-western region, was blamed for a series of attacks and kidnappings.
"We have been after this woman who did such damage to Antioquia and the whole region of Uraba for a long time," Mr Santos said.
Columbian President Alvaro Uribe had recently given a public assurance to Moreno that he would guarantee her safety if she handed herself in.
