Police have arrested 10 more protesters in Charlotte, N.C., on the Democratic National Convention's last day.

Authorities say three demonstrators were detained Thursday for blocking a downtown street, and one for hanging a banner without permission.

Six protesters were taken away in handcuffs earlier Thursday near the corporate headquarters for Duke Energy. They had locked arms and were sitting on top of a banner claiming that the energy company was harming the environment.

Two dozen officers surrounded them and eventually lifted up the protesters, who refused to move. They then put them into prisoner transport vans.

Counting Thursday's detentions, a total of 25 protesters were arrested or taken away in handcuffs during the three-day convention, which ended Thursday night.

Several sit-ins that blocked traffic this week ended without arrests.
