Protesters convened outside Philadelphia police headquarters and marched to City Hall late Thursday afternoon to rally against the decision of officers to arrest two black men at a Center City Starbucks last week, an incident that has sparked national outrage.

The march was organized by POWER, an interfaith group that helped lead Monday's sit-in at the 18th and Spruce Streets location where the incident occurred last Thursday. Earlier this week, members of the group met with Starbucks CEO Kevin Johnson and chairman Howard Schultz about the incident.

Thursday's protest came hours after Philadelphia Police Commissioner Richard Ross publicly apologized to the men, Rashon Nelson and Donte Robinson, who were arrested for sitting in the store without making a purchase. Ross initially said "officers did absolutely nothing wrong," a comment that drew outrage from activists and stirred POWER to hold Thursday's march.

Here is a recap of the event.
