The police have officially returned to the University of Puerto Rico at Rio Piedras on the orders of Governor Luis Fortuño. This is the regular police, who according to William Ramirez of the Puerto Rican ACLU, have actually never left the campus.

According to El Nuevo Dia, the riot police have not been called to campus but remain on alert and nearby in case, according to Fortuño, “A violent group tries to bring violence and intolerance to the University”.

There were incidents of violence on campus yesterday due to some students blocking at least one entrance to the campus as part of a a strike action. The incident that I witnessed via video was a professor physically attacking students blocking the entrance and students responding in self-defense. The governor has called the student strike a “dictatorship”.

The violence of the police against the student protesters is the focus of close scrutiny of the Puerto Rican ACLU which released a report calling the situation a human rights crisis (PDF file).
