Yahoo! News - NYC Police Arrest 250 in Bicycle Protest
NEW YORK - In the first major clash between police and demonstrators converging for the Republican National Convention, more than 250 bicyclists were arrested during a protest ride that snaked through the city and passed by Madison Square Garden.

Bikers chanted anti-Bush slogans, stifled traffic and, in some places, argued with motorists during the Friday night ride, which began at Union Square and drew thousands of cyclists.

Deputy Police Commissioner Paul Browne said the bikers had caused "massive disruptions" and endangered motorists. Participants said their ride was peaceful and that the arrests were an excessive show of force.
