TULSA, Okla. (AP) - Protesters with the Occupy Tulsa group have again been arrested for violating the city's park curfew.

Officer Jason Willingham says 13 people were arrested after 11 p.m. last night at H.A. Chapman Centennial Green. The arrests come after 10 people were arrested about 2:30 a.m. Wednesday after city officials decided to begin enforcing the 11 p.m. to 5 a.m. curfew at city parks.

Willingham says those arrested last night did not actively resist and pepper spray was not used - as it was while making the first arrests.

Members of the group began camping at the park Friday in protest of what they call corporate greed and say they plan to ask the Tulsa City Council for a permit to allow them to remain in the park during curfew hours.
