A number of Wall Street protesters have been arrested in New York during scuffles with police as they marched towards the city's financial district.

According to BBC, the confrontation came after activists averted a showdown with authorities who agreed not to move them from a park. Demonstrators said officials' plan to clean Zuccotti Park, where they have been based for weeks, had been a ploy to evict them.

The protests against corporate greed have spread to other U.S. cities. Several demonstrations are reportedly planned this weekend in Canada and Europe, as well as Asia and Africa.

Fourteen arrests were made on Friday in Lower Manhattan. In the Colorado city of Denver, around two dozen demonstrators were detained as police removed their tents in Lincoln Park near the state Capitol. And 10 Occupy Seattle protesters were held on Thursday when they ignored orders to leave their tents in the city's Westlake Park, said police.
