The court found Jorge Noguera Cotes, a former director of the Security Service agency of Colombia DAS, guilty of infiltrating intelligence to paramilitary groups, El Espectador reported Wednesday.
Cotes was sentenced to 24 years in prison for criminal conspiracy and illegal use of privileged information.
He was also held responsible for the murder of university Professor Alfredo Correa de Andreis, who was assassinated after Cotes passed information about Andreis to paramilitaries.
Cotes was appointed head of the intelligence agency by President Alvaro Uribe in 2002.
He was arrested in 2007 under charges of conspiracy to commit crime and murder but was later released.
