Press TV reports.
Eyewitnesses say officers of the New York Police Department (NYPD) were waiting in ambush for Occupy Wall Street protesters returning from the so-called Occupy Guitarmy 99 Mile March in Philadelphia on Wednesday.
At least two protesters were arrested and a woman was injured during the NYPD crackdown on the peaceful demonstrators.
The march was to have concluded at landmark Zuccotti Park when NYPD officers pounced on demonstrators and independent media reporters.
The unprovoked police crackdown resulted in injuries and a number of arrests.
The Occupy Wall Street movement began when a group of demonstrators gathered in New York's financial district on September 17, 2011 to protest against corruption, the unjust distribution of wealth in the country, and the excessive influence of big corporations on US policies.
