ET ] . ( CNN ) -- In cities across the United States , marchers took to the streets to show support for protesters in Baltimore and to complain about police violence in their own towns . On Wednesday night , several hundred people streamed into Union Square for an `` NYC Rise Up & Shut It Down With Baltimore '' rally . Protesters headed west on 17th Street and were met by New York City Police officers who pushed them back . A small scuffle broke out between the two front lines and police placed at least 20 people in zip ties in the street . The NYPD also handed out fliers and used loudspeakers to tell protesters and pedestrians to stay on the sidewalk . One person was placed in ambulance and taken away . The crowd headed toward Times Square . A law enforcement source told CNN that more than 60 people were arrested during the demonstrations . The rally was organized through social media , much like protests over the killing of Eric Garner , who died while police held him in what appeared to be a chokehold . The demonstrators chanted `` Black Lives Matter '' and `` Justice for Freddie Gray '' -- the Baltimore man whose death sparked street confrontations in Baltimore . CNN affiliate WCBS reported Mayor Bill de Blasio sent a message to the protesters : `` I 'd say that if you want to make change , keep things peaceful . '' A smaller rally was held Tuesday in New York . In Washington , about 500 protesters , mostly in their 20s , gathered in the middle of H Street and 7th and chanted , `` All night , all day , we 're gon na fight for Freddie Gray . '' The mood seemed more festive than confrontational , with songs by Public Enemy like `` Fight the Power '' playing and sign-language interpreters translating the music and chants . The protest moved to the White House where most of the crowd dispersed . It started after most office workers had headed home and did n't disrupt the Washington workforce badly . One of the groups involved in the protest is the DC Ferguson Movement . Organizer Eugene Puryear said the march was called to show solidarity with the residents in Baltimore and to highlight that police brutality is a national issue . Several hundred people gathered in Gold Medal Park in Minneapolis for a rally organized by the group of # BlackLivesMatter . The Minneapolis group held similar events in the past in response to alleged police brutality across the country . Protests also were held in Boston and Houston . On Tuesday , violent protests took place in Ferguson , Missouri , where three people were shot , the city police reported . Police said they did n't do the shooting . A 20-year-old man was arrested and the three victims were in stable condition -- two with wounds to the neck , one in the leg , police said . Police said about 300 people marched , with protesters throwing rocks at police , damaging four police cars and setting trash and debris on fire near Northwinds Estates and West Florissant , police said . One business in Dellwood was damaged , police said . No officers were injured as police conducted anti-riot activities until 3 a.m . In Los Angeles , six people protesting against police brutality were arrested Monday night when they failed to disperse , reported CNN affiliate KABC . About 50 people marched , KABC said . On Tuesday , protesters gathered outside the Stapes Center , where the Los Angeles Clippers and the San Antonio Spurs were playing an NBA playoff game . They disrupted traffic and carried protest signs . In Chicago , hundreds of protesters marched Tuesday from police headquarters at 35th and Michigan through the Southside , CNN affiliate WGN reported . Police made one arrest , for reckless conduct . WGN said protesters spoke about police violence and the death of Rekia Boyd , who was killed by an off-duty officer in 2012 . That officer was acquitted last week . The group plans to gather Wednesday night at the DePaul Law School . About 100 people marched Monday night in Oakland in support of Baltimore protesters , reported CNN affiliate KABC .
