Columbia ? A city council member in Colombia was arrested Saturday – while giving a live radio interview by telephone – for allegedly masterminding a guerrilla attack that killed nine of his colleagues.

The suspect, Pedro Gil Trujillo, is a council member in the town of Rivera, 150 miles southwest of the capital of Bogota, where the attack occurred in February.

On Feb. 27, members of the Revolutionary Armed Forces of Colombia, or FARC, disguised as police, walked into a hotel and opened fire while Trujillo and his fellow council members were attending a lunch meeting.

Nine councilors were killed during the massacre, one of the worst in recent years targeting Colombia’s politicians. Trujillo escaped with minor injuries.

Trujillo allegedly alerted the rebels to the meeting beforehand, a spokesman for the attorney general’s office said.

Trujillo denied the charges on air during an interview with Caracol Radio, seconds after judicial police burst into the northern Bogota home where he was staying.
