A video posted to social media shows the group of teenagers on bicycles arguing with a woman along the Brickell Avenue Bridge.
“Don’t touch me, you bunch of thugs,” the woman says as she walks away from the group.
The woman has then joined an armed white man, who confronts the teens.
The man screams obscenities and racial slurs at the teens, telling them to leave.
The confrontation took place around 5:30 p.m. Monday, according to Dream Defenders Action, the group that posted the video on social media.
The group said the teens were protesting the redevelopment of the Liberty Square public housing complex.
In another video shot before the confrontation, one teen held a sign that read, “Save Liberty Square.” That video shows the woman pleading with the teens who were blocking the road. “I have kids I need to pick up. This isn’t funny. Please move your bikes,” she says in the video.
