A pair of pre-dawn confrontations between Austin police and Occupy Austin protesters led to 38 arrests Sunday, October 30, The Associated Press reported

Most were charged with criminal trespass, Police Chief Art Acevedo said. No injuries were reported.

The first confrontation came about 12:30 a.m. Sunday when officers moved to enforce a new rule banning food tables in the City Hall plaza between 10 p.m. and 6 a.m. Some protesters surrounded the tables with arms linked.

Another incident came about 2 a.m., when more than 50 police officers moved to clear an amphitheater on the plaza for a regular power-washing.

Most of the protesters remained peaceful and stayed out of the way of the cleaning, but some wouldn't move and were arrested when confronting officers.
