Officers filed into a park that has been seized by Occupy Charlotte protesters for months and began forcing them out of the area.
Many protesters refused to leave the area. Others refused to leave their tents. Police arrested seven protesters.
The new rules approved by Charlotte City Council give police more power to stop and search people when the Democratic National Convention comes to town in September.
But a major part of the ordinance outlaws camping overnight on city property.
Protesters were told they were welcome to remain at the site -- but without the tents.
