DENVER (AP) -- Occupy Denver supporters are rallying with May Day marchers calling for workers' rights around the world.
Nearly 200 people marched downtown on Tuesday on Broadway before turning onto the 16th Street pedestrian mall, blocking the mall's buses and traffic on intersecting streets as they walked.
The marchers also stopped in front of the Federal Reserve Bank. Police officers accompanied the marchers but didn't try to interfere.
After about two hours of marching through downtown, the demonstrators returned to their starting point, a park near the state Capitol.
Denver Police Department says one person has been arrested on a charge of public fighting.
After dark, supporters planned to participate in an outdoor "slumber party" to protest a proposed ban on unauthorized camping in Denver.
