FARC guerrillas released two construction workers who they kidnapped last week in Meta, a province in central Colombia, police said.

A woman, meanwhile, was rescued by police from the common criminals who had abducted her.

The construction workers were kidnapped last Friday by the 27th Front of the Revolutionary Armed Forces of Colombia, or FARC, Meta police commander Gen. Jaime Alfredo Romero told reporters.

The FARC released the captives under heavy pressure from the security forces, Romero said.

The rebels were demanding a ransom of 70 million pesos (about $39,000) for the two workers, who were abducted in Puerto Rico, the police chief said.

The FARC, Colombia's oldest and largest leftist guerrilla group, is on both the U.S. and EU lists of terrorist groups. Drug trafficking, extortion and kidnapping-for-ransom are the FARC's main means of financing its operations.

Police rescued the kidnapped woman in Cundinamarca province, where Bogota is located.

Five adults and a minor were arrested for the woman's kidnapping. EFE
