Aide to Colombia Presidential Candidate Arrested on Spy Charge
Advisor to Oscar Ivan Zuluaga Charged With Intercepting Emails of President, Chief Rebel Negotiator
An adviser to a leading candidate in Colombia’s presidential election was arrested Tuesday and charged with heading a spy ring that allegedly intercepted the emails of President Juan Manuel Santos and the Marxist rebels’ chief negotiator in peace talks with the government.
Attorney General Eduardo Montealegre read the charges at a news conference after authorities raided a Bogotá office and arrested Andres Fernando Sepulveda, who is an adviser to Oscar Ivan Zuluaga. Mr. Zuluaga, a conservative supported by former President Álvaro Uribe in his quest to win the presidency on May 25, is in second place in the latest polls behind Mr. Santos, who is seeking re-election.

The attorney general said that the spy ring’s objective appeared to have been to sabotage the peace talks, which began in November 2012 and are being held in Havana, Cuba. Mr. Montealegre said investigators had not determined who was benefiting from the information.
