(CNN) -- What started as the Occupy Wall Street movement in New York in September has spread across major cities worldwide as a call to action against unequal distribution of wealth.
Here is a roundup of some of Saturday and Sunday developments.
Protesters returned to the streets of Atlanta on Sunday night, a day after a police crackdown on a gathering organized by the movement resulted in the arrests of 19 people.
About 80 people converged on the city's Centennial Olympic Park for a peaceful gathering, according to police. The group was scheduled to return to Woodruff Park, the site of Saturday's arrests, later in the night to hold a "Nonviolence Training Seminar."
Those arrested Saturday either refused to leave Woodruff Park after the 11 p.m. closing time or blocked nearby streets, the Atlanta Police Department said.
Authorities charged one protester with aggravated assault and obstruction after they said he assaulted a motorcycle officer patrolling the area.
However, demonstrators said the officer "accelerated into a demonstrator."
After incidents of sexual harassment in Zuccotti Park, a women-only tent has been set up for the Occupy Wall Street protesters.
The tent holds about 15 women. A sign on the front reads: "Women's Safe Sleeping Space."
Last week, New York police charged a 26-year-old Brooklyn man with sexual abuse for allegedly inappropriately touching an 18-year-old woman at the park, the home base for the protests.
Another new feature for the encampment: toilets.
Three toilets were installed at a building two blocks from the park. The toilets, donated by supporters, will have round-the-clock security presence and will be serviced once a day, said Han Shan, a spokesman for the protesters.
On the 22nd day of Occupy Orlando, hundreds of people marched from the group's base at the Johnson Park to Orlando City Hall on Saturday, some chanting, "The banks got bailed out (and) we got sold out," according to CNN affiliate WESH.
The police-escorted "People over Profits" march did not result in arrests. It coincided with Bank Transfer Day, a social-media driven campaign urging consumers to withdraw their money from banks in favor of credit unions.
A Chase Bank branch in Portland, Oregon, was vandalized on Saturday, police said in a statement. Windows of the building were broken and paint thrown inside. Hours later, officers responded to a report of windows broken out of a Wells Fargo bank branch, police said.
Late Saturday, an e-mail from "The Real Occupy Portland" was forwarded to Portland police from a media outlet. In the e-mail, the group claimed responsibility for the vandalism at both buildings and said the incidents were connected to Bank Transfer Day.
But police later received an e-mail from a group calling itself "The Real Occupy Portland and the 99%," saying the group was not connected to the vandalism and "does not condone any vandalism or violence." The first e-mail was sent from an anonymous address, the group said, citing media reports. The investigation into both cases was ongoing, authorities said.
Police in Sydney, Australia, dragged away several protesters Saturday after they refused to comply with an order to take down a tent set up at the city's Hyde Park.
Authorities made two arrests, but a woman in the tent at the time managed to escape "with the assistance of the crowd, which became hostile toward the officers," the New South Wales Police said.
On Sunday, police kept an eye on further protests. Earlier Saturday, about 400 people made their way from outside Sydney Town Hall to a mall at the center of the city.
Vancouver's mayor has asked that the tent city at the city's art gallery be cleared after a woman was found dead at the encampment Saturday, the Canadian Broadcasting Corp. reported.
Authorities have not determined how the woman -- thought to be in her 20s -- died, but police said in a statement "no evidence has been uncovered at this early stage in the investigation to suggest the death is suspicious."
"I have directed the city manager to expedite the appropriate steps to end the encampment as soon as possible, with a safe resolution being absolutely critical to that," the CBC quoted Mayor Gregor Robertson as saying Saturday night.
Authorities will not charge a motorist who struck three protesters Friday night during a demonstration in Washington, Assistant Police Chief Lamar Greene said Saturday.
The three hit outside Americans for Prosperity event in the nation's capital were taken to a hospital, treated and released. Occupiers were blocking streets around the Washington convention center in protest against a conservative conference. The motorist had a green light, police said Saturday.
Occupiers were upset there was no citation and no arrest, police said
Caleb Hays, who shot a video of the hit-and-run, said protesters had converged on the area.
"One lady jumped on the hood as the car screeched to a halt. As they stepped back, the driver tried to leave. At that point, the driver hit the woman who had jumped on his car. He sped off as she lay on the ground, unmoving.'
Police made two other arrests for disorderly conduct Friday night.
