Officer hit by trolley, 2 arrested trying to board another trolley at Sounders parade

SEATTLE -- Thousands and thousands of fans turned out Tuesday to support the MLS Cup Champion Seattle Sounders FC, and Seattle police reported several incidents.

Officers arrested two people who police say tried to board Emerald City Trolleys that Sounders FC players were riding on during the march.

Police tweeted "#SoundersMarch etiquette pro-tip: Don't try & board the @SoundersFC trolleys. Two people under arrest for this so far. ⚽️🏆😱"

Later Tuesday, police said a bike officer was hit and injured by one of the trolleys near the parade route at Queen Anne Ave. and Mercer St.

Few details were immediately released.
