PO march to Plaza de Mayo

The Workers Party (PO) marched to Plaza de Mayo square to claim over the disappearance of Alfonso Severo, one of the main witnesses on the trial of activist Mariano Ferreyra's crime.

The head of the PO, Jorge Altamira, told the press that Thursday's march had been "organized in the last minute and spontaneously via social networks" to show a rapid reaction towards the disappearance of the witness.

The disappearance of the witness recalled Jorge Julio López disappearance back in 2006 during the trial against repressor Miguel Etchecolaz.
