DALLAS (CBSDFW.COM) – A protest over switching banks by the group MoveOn.org and the continued Occupy Dallas movement turned into a tense scene Saturday.

The protest, to mark what organizers were calling Bank Transfer Day, was held at the Bank of American building at 901 Main Street in downtown Dallas.

According to the city of Dallas, at 1:00 p.m. several of the protesters climbed up on to planters near the front entrance of the building. When ordered down, police say one of the protesters ‘became aggressive’ and assaulted an officer.

Protesters tell a different story, saying an officer pushed the man off the planter, injuring him.

A scuffle then broke out between police and protesters that ended with 8 protesters being arrested and three officers suffering from minor injuries.

The protesters said police used pepper spray and were inciting a peaceful demonstration. After the incident at Bank of America, members of the protest marched through downtown with a heavy police presence close behind.

All told between 150-200 protesters participated in Saturday’s march.
