About 30 protesters who were part of the "Occupy Wall Street" movement in Nashville, Tennessee were released Friday after being arrested on trespassing charges.
The protesters were arrested in the early-morning hours for violating a new nighttime curfew on a downtown plaza where they have been gathering for the past few weeks.
In the California city of Oakland, medical officials said Friday that the status of Scott Olsen, an Iraq war veteran, has been moved up from critical to fair, after his skull was fractured during a police attempt to evict the protesters from a public square.
Several hundred people held a vigil for Olson Thursday evening at the square, two days after the violence broke out. Also Thursday, Oakland Mayor Jean Quan released a statement saying she was "deeply saddened" about Tuesday's violence and added that her administration is investigating the use of force by police officers.
Police used tear gas and bean bag bullets to disperse the protesters, some of whom were throwing rocks, paint and other debris at police.
City officials say they will allow protesters to assemble from 6 a.m. to 10 p.m., but that no camping will be allowed overnight on public property.
The "Occupy Wall Street" protests, which began in New York last month, are part of a loosely organized movement protesting corporate greed, economic inequality and high unemployment.
Affiliated protest groups have sprung up in dozens of cities across America, as well as countries around the world.
