During a walkout gun violence protest at a Chicago high school, police arrested just one teen out of a large group for walking on a busy street.

Pete Grieve, the student editor-in-chief of the University of Chicago's Chicago Maroon newspaper, posted video of Kenwood Academy junior Aminah Glenn being taken away by police in handcuffs as he and her classmates followed them.

"What did she do?" a person in the video asked the police as they took Glenn away.

Following the student's arrest, Kenwood senior Simone Iroegbu told Grieve that they would not be returning back to school until they learned what was happening with Glenn. Iroegbu said she and her classmates had repeatedly called the Chicago Police Department and were arranging for legal representation for her prior to her release a few hours later.

Irogebu noted that Glenn was arrested for entering the busy Lakeshore Drive, but that many others walked on the street with her, causing her arrest to appear suspicious in her eyes. Grieve provided video of many others running onto Lakeshore as well.

In a statement, CPD said the student was arrested for "disrupting traffic" and "reckless conduct." Another journalist, Elizabeth King, soon learned that charges against Glenn had been dropped.
