About 500 people, including activists from the Occupy Wall Street movement, marched through New York on Saturday in protest at police abuses.

The demonstration through Manhattan marked the nationwide Annual Day of Protest to Stop Police Brutality.

However, the rally came under extra attention this year against the background of the anti-establishment protest camp near Wall Street and its growing number of imitators around the world.

Police "defend the one percent," one placard read, referring to the Occupy Wall Street movement's slogan of "We are 99 percent."

"Hey, hey, hey, how many kids have you killed today?" the crowd shouted, echoing a Vietnam War-era chant.

Police turned out in force to ensure the demonstrators did not block traffic as they marched through the city, but the event passed peacefully.

The demonstration came a day after Occupy Wall Street activists in New York were joined by veteran folk singers Pete Seeger and Arlo Guthrie at a march where more than 30 people were reported arrested.

Earlier Friday, a march in Harlem against the New York Police Department's controversial policy of stop-and-frisk ended when some 30 people were arrested, including civil rights campaigner and Princeton University professor Cornel West.

One participant at Saturday's rally said he was disappointed at the turnout.

"We need bigger numbers -- five or 10 million -- and then they'd listen. This is not enough," said David, 28, who did not want to give his last name.

Occupy Wall Street is now in its sixth week, with the symbolic center at the Manhattan protest camp targeting what participants say is corporate influence over politics and lack of opportunity for those outside the business and political elite.
