ASUNCION Ė Paraguayo Cubas, an anti-corruption activist who arrived in Asuncion last week after completing a 300-kilometer (186-mile) walk, remains jailed Monday for leading a demonstration outside Paraguayan Attorney General Javier Diaz Veronís residence.
Cubas was arrested Sunday while painting slogans in front of Diaz Veronís house in a protest in which Ciudad del Este councilman Celso Miranda was also detained and a number of people were injured.
Cubasís supporters said they would rally Monday around the police special response unitís station to demand his release.
Cubas was arrested for causing a public disturbance, police said.
The attorney leads a movement that fights public corruption and has come out against a constitutional amendment to allow presidential re-election.
The amendment is backed by the governing Colorado Party and opposed by some Colorado dissidents and the Liberal Party.
Cubas and Miranda walked for 12 days from Ciudad del Este, Paraguayís second-largest city, to Asuncion.
On arriving in Asuncion, the marchers camped in the central Plaza de la Democracia and started painting anti-corruption graffiti on the walls of several government agencies.
Transparency International said in a report released last week that Paraguay was perceived as one of Latin Americaís most corrupt countries along with Mexico and Honduras, and topped only by Venezuela, Haiti and Guatemala.
