Líber Arce

On 13 June 1968, Swift Security Measures [es] had been decreed by the government, a state of emergency that would be maintained for months.

At noon on 12 August 1968, a group of dental, medical, nursing, and veterinary students set out from the Faculty of Veterinary Medicine, located on the street then called Larrañaga, on the way to Rivera Avenue. This "lightning demonstration" was intercepted by a police vehicle with an officer and three agents who were present. Officer Enrique Tegiachi fired on the group. There Líber Arce was wounded in the left groin, causing a hemorrhage.

On Friday, 20 September 1968, the police suppressed another demonstration of students against the government policy of Pacheco Areco, opening fire with riot shotguns and killing Susana Pintos (28) and Hugo de los Santos (19).

Since 1968, 14 August has been adopted by the Uruguayan student movement (university and secondary) as Student Martyrs Day.

Líber Walter Arce Risotto (30 October 1938 – 14 August 1968) was the first student killed by police forces in Uruguay under the government of Jorge Pacheco Areco.

After the return to democracy, General Prim Street (in homage to the Spanish military officer and politician Juan Prim, 1814–1870) was renamed Líber Arce. The street begins at the doors of the Veterinary School and passes behind the municipal zoo of Villa Dolores [es].
