As the new year dawned with public transportation fare hikes in some major Brazilian cities, the Free Fare Movement, a leading force in mobilizing for cheaper tickets, organized multiple demonstrations across the country — sometimes met with violent crackdowns from the police.
In São Paulo, bus, train and subway fares increased from 3.50 reais (0.85 US dollars) to 3.80 (0.92 US dollars), while in Rio de Janeiro the fare rose from 3.20 to 3.50. State and city governments blame  Brazil's high inflation rate — the highest in 12 years  — and rising costs of electricity for the hikes: Protesters, however, are demanding a thorough revision of transportation  policies that rely on private enterprises, claiming these business make a generous profit out of public subsidies.
A study carried out in 2015 by Fundação Getúlio Vargas, a local research center, found that public transport in 21 Brazilian cities are among the most costly in the world  in relation to the average salary, outranking cities like London, Tokyo and New York. The study calculated how many minutes the average employee needs to work in order to afford a single journey bus ticket — 13.3 minutes in São Paulo, 13.2 in Rio de Janeiro, 11.3 in London, 6.5 in Tokyo and 5.8 in New York.
In June 2013, protests against a fare hike also led by the Free Fare Movement triggered the largest demonstrations in a generation  in Brazil, with their political implications still being debated to this day. In early 2015, the movement once again mobilized protests against another fare hike, but this time they didn't pick up speed as before because a different group of protesters stole away the media spotlight  for demanding the impeachment of President Dilma Rousseff.
So far in 2016, six demonstrations have taken place, four of them in São Paulo alone. The first two, January 8 and 12, were the most violent, with police firing rubber bullets and tear gas at protesters, leaving dozens injured , some seriously. On January 12, the protest was cut short  by the police following a disagreement with organizers over the route of the march. Police accused protesters of damaging public and private property, and more than 25 people were temporarily detained.
Demonstrations were widely tweeted and dozens of photos and videos have sprung up online. The one below was recorded in São Paulo on January 12:

Among the injured on January 12 was a homeless man who was collecting cans  in the area, hit by a rubber bullet in the leg. Another was subway employee Heber Veloso , who says he was beaten up by the police. One protester was shot in the eye with a rubber bullet , but isn't at risk of losing his vision, while another suffered a hand fracture  and had to undergo surgery.
During the third demonstration on January 14, protesters complained of the disproportional amount of police officers deployed to follow them, accusing the state government — who controls the police forces — of ‘psychological terrorism’.

Former students of mine and of @Hupsel report via message the impossibility of getting into the demonstration with so much police. Psychological terror!

Some women at the third demonstration accused military police of sexual abuse. Seven reported being beaten  by military police officers; another group of around 15 people said police officers beat them as well and touched the vaginas of the women  amongst them.
The protests managed to gain support from other social movements in São Paulo such as the Homeless Workers Movement (MTST), which has a solid base in the city's poor suburbs (the Free Fare Movement in contrast finds most of its support amongst students). During a demonstration held on January 19, the Homeless Workers Movement gathered 5,000 people  in São Paulo's Itaquera district in the city's far east, where World Cup Stadium Arena Corinthians  is located, and in Capão Redondo, in the city's south.
Independent journalism agency Democratize summarized  the day:
Fortalecido com o apoio de movimentos como o MTST, protestos contra a tarifa ganham peso nesta semana. Com quatro manifestações simultâneas em pontos diferentes da cidade, mais de 30 mil pessoas participaram de mais um dia de luta contra o aumento da tarifa no transporte público em São Paulo.
Strengthened by the support of movements like the Homeless Workers Movement, fare protests gained momentum this week. With four simultaneous demonstrations in different parts of the city, more than 30,000 people took part in another day of struggle against the fare increase in public transportation in São Paulo.
A fifth demonstration in São Paulo has been called  for January 21, although it remains to be seen whether those demonstrations will gain the momentum of those in June 2013  or if they will succeed in pressuring state and city governments to revoke the fare hikes once and for all and not for just a few months.
