Angry protesters attacked the mayor of a small city in Bolivia on Wednesday, hacking off her hair, dousing her with red paint and dragging her barefoot through the streets amid country-wide clashes over the results of a recent election.
According to Vice President Garcia, the violence happening all over the country was the first for Bolivia.

In nearby Vinto, an opposition mob stormed the municipal headquarters and dragged the mayor, Patricia Arce, into the street before setting the building ablaze.
Mr Morales said in a tweet that Ms Arce - a member of his ruling Movement for Socialism (MAS) party - had been "cruelly abducted for expressing and defending her ideals and the principles of the poorest".
Disgusting images of the mayor show her covered in red paint, her hair cut, and her body covered in dirt.
"The Right says 'Evo has to resign.' I want to tell you, sisters and brothers, to all of Bolivia and the world, I will not resign", Morales said at a public event. The MAS has blamed opposition protesters for attacking Arce. They also forced her to sign a resignation letter and torched parts of city hall. Her office was set alight and the windows of the town hall were smashed.
Limbert Guzmán, a 20-year-old student, died late on Wednesday in a clinic in the city of Cochabamba, and two others were fatally shot last week during unrest in Santa Cruz province, an opposition bastion.
"We condemn the violent actions that cause grief and pain in the Bolivian family", Morales added.
Mesa, the runner-up in the October 20 vote, and civic leader Camacho, have been calling instead for Morales - the country's leader since 2006 - to step down and to hold new elections without him. Opponents challenged an official count that showed Morales winning with 47% of the vote and a margin of just over 10 percentage points over his nearest competitor, enough to avoid the need for a runoff against a united opposition.
The government said on Friday that an audit of the contentious presidential election would likely be completed early next week, which could either back Morales' victory or throw open the door to a new vote.
