Colombian prosecutors on Thursday launched an investigation into alleged illegal spying on journalist Vicky Davila, the director of La F.M. radio's morning news program.

"The Attorney General's Office has opened an investigation into illegal surveillance and wiretapping of journalist Vicky Davila," the AG's office said on its Twitter account.

The prosecutor's office said journalists "are subject to special constitutional protection" and that threats against them for carrying out their work constitute an "affront to the democratic system."

The investigation stems from a complaint filed by Davila in which concrete evidence was presented showing that the journalist, her family and news team "have been victims of illegal surveillance and wiretapping of their private communications," Attorney General Eduardo Montealegre said.

The AG's office suspects the illegal eavesdropping may be related to news reports about alleged irregularities within Colombia's National Police force, Montealegre said.

Senior National Police officials may be summoned for questioning in the case, he added.

This latest probe into illegal spying calls to mind a massive scandal during former President Alvaro Uribe's administration involving illegal wiretapping and surveillance carried out against judges, journalists, politicians and human rights activists.

Colombia's Supreme Court in April handed down a 14-year prison sentence to former intelligence chief Maria del Pilar Hurtado for illegal surveillance that targeted, among other individuals, Daniel Coronell, who is now Univision's executive vice president and executive director of news; and Gustavo Petro, the outgoing mayor of Bogota.

Prosecutors had been seeking a 20-year sentence for Hurtado, who headed the now defunct DAS intelligence agency when the spying occurred - between August 2007 and October 2008.
