PORTLAND -- Three men were arrested during an Occupy protest at Mt. Tabor Park Friday.

According to Sgt. Pete Simpson of the Portland police, Michael Meo (pictured left), 66, was was found in the park near a reservoir putting signs in the ground and stringing them in a tree.

Police asked Meo to remove the signs and leave the park. When he refused, Meo was arrested for criminal trespassing and taken to the Multnomah County Jail.

At around 9:15 p.m., police arrested 42-year-old Troy Thompson (pictured center) after he pitched a tent in Mt. Tabor park, which is a violation of park rules, police said.

Just after midnight, police arrested 22-year-old Erik Zimmerman (pictured right) of Lake Oswego after he refused to leave the park at closing.

A group of people associated with the Occupy movement were protesting a cap that is planned to be put on the open-air reservoir at the park on Friday.

Protesters were upset that city leaders stopped fighting the federal requirements to either cap or close Portland's open-air reservoirs.

Portland leaders took action to stop hundreds of Occupy protesters from taking over Mount Tabor park on Friday night.

The city closed all gates that offer vehicle access up to the reservoir.

City leaders said it's a federal decision and there's not much it can do. Police are concerned about problems with protesters after the park closes at midnight.

On Wednesday, protesters banged on pots and pans outside of Portland's City Hall in an effort to make their message about the Mt. Tabor reservoir heard.
