80 arrests at Wall Street protest
About 80 people have been arrested as demonstrators who were camped out near the New York Stock Exchange marched through lower Manhattan.
The Occupy Wall Street protest is entering its second week. Demonstrators said they were protesting bank bailouts, the mortgage crisis and Georgia's execution of Troy Davis.
At Manhattan's Union Square, police tried to corral the demonstrators using orange plastic netting. Some of the arrests were filmed and activists posted the videos online.
Police said the arrests were mostly for blocking traffic. Charges include disorderly conduct and resisting arrest. But one demonstrator was charged with assaulting a police officer, who suffered a shoulder injury.
Protest spokesman Patrick Bruner criticised the police response as "exceedingly violent" and said the protesters sought to remain peaceful.
