Tucson police arrested 53 people overnight for staying in Armory Park after closing time as part of an anti-Wall Street rally.

Police said that about 150 people taking part in "Occupy Tucson" remained in the park at closing time at 10:30 p.m. Saturday. Those remaining were told that they would be arrested for violating a city ordinance dealing with being in a city park after closing.

Many of those demonstrators left voluntarily at that time, according to a Tucson police news release. Those that didn't were issued a citation and released. Tucson police said citations were issued until about 1:30 a.m. Sunday and officers then left the park. No disturbances were reported as officers issued the criminal citations.

Those cited will have to appear in court at a later date.

Meanwhile, police arrested 46 people for criminal trespassing in Phoenix following an anti-Wall Street rally.

Saturday's arrests came hours after anti-Wall Street protesters gathered in Phoenix and Tucson as part of a series of protests across the country against financial institutions.

Phoenix police spokesman Sgt. Trent Crump says protesters marched from a downtown rally at Cesar Chavez Plaza to Margaret T. Hance Park on Saturday evening and the park had posted 10:30 p.m. closing time.

Crump says some protesters refused to leave and officers moved in to clear the park, resulting in 46 arrests for misdemeanor criminal trespass.
