Protesters gathered in Hyde Park Monday alleging the University of Chicago police used unwarranted violence against demonstrators Sunday night.

The group, which calls itself "Fearless Leading by the Youth," was protesting the lack of an adult trauma center at the university's hospital.

Three people from the group were arrested and charged with misdemeanors. They were released from police custody Monday morning.

Protestors say they will deliver a petition to university administrators, asking for an explanation.
