Four Colombian journalists covering May Day demonstrations in Medellín were attacked by riot police in spite of showing their press cards.
Andrea Torres, Sebastian Carvajal, Juan Fernando Rojas and Esteban Vanegas - all from the daily El Colombiano - were assaulted by riot officers to whom they had made a point of showing their press cards.
Vanegas, a photographer, was held for 12 hours after being accused of assaulting public servants.
Camille Soulier, head of the Americas desk with the press freedom watchdog, Reporters Without Borders, said: "This attack took place just over a month after the United Nations approved a resolution on the need to protect journalists covering peaceful demonstrations.
"We urge the public prosecutor to drop all charges against the journalists concerned and to investigate the police officers who attacked the journalists."
