Police in Ferguson, Mo., arrested a number of protesters late Thursday night after a scuffle broke out while Police Chief Tom Jackson was walking with the crowd, KMOV.com reported.
Officers responded by pushing demonstrators back across the street and making arrests:
"The right of the people to peacefully assemble is what the police are here to protect. If anyone who was peacefully exercising that right is upset and angry, I feel responsible and I'm sorry," Jackson stated.
Despite this effort, protesters gathered in downtown Ferguson called for Jackson's resignation.
The exact number of protesters who were arrested was not released.
Brown, 18, was shot and killed by Ferguson police officer Darren Wilson on Aug. 9. The case is currently before a grand jury in St. Louis County, and under investigation by the U.S. Department of Justice.
Since the shooting, the mostly black community has seen weeks of racially charged protests and bursts of violence. Demonstrators have vowed to continue protesting until Wilson is arrested and charged in Brown's death, Reuters reported.
