Ferguson protesters marched again in New York City on Monday, this one part of a nationwide walkout involving students who walked away from class.
Students from LaGuardia, Manhattan Business and Hudson high schools were among the protesters who marched from Union Square to Times Square earlier in the day.
"Yet another shooting of an unarmed black man has occurred, and the anger's just built up so something needs to be done," said Emma Morgan-Bennett, a student at Bard High School Early College.
The protesters carried signs reading "Ferguson is everywhere" and "I might be next," and chanted "Hands up, don't shoot" as they marched. Police were lined along the streets and did not interfere with the protesters, who were mainly sticking to the sidewalks and not disrupting traffic.
Seven people were arrested in Monday's demonstrations, police said.
There have been arrests on each day of the Ferguson protests in New York City since last week, but the demonstrations have been non-violent, with no reported injuries to either protesters or police officers. There were isolated clashes with police, and some disruptions on highways and bridges last Tuesday.
Monday's walkouts stretched from New York to San Francisco, and included Chicago and Washington, D.C.
At the University of Missouri-St. Louis, three dozen students rallied outside the library and walked out of class, some with their hands up in the gesture that has become a symbol of the movement.
The walkouts came a week after a St. Louis County prosecutor's announcement that a grand jury had decided not to indict white Ferguson police officer Darren Wilson in the August shooting death of 18-year-old Michael Brown, who was unarmed and black. The case spawned sometimes violent protests, often with demands that Wilson face charges.
Wilson has resigned from the police force.
