Barkin tweeted that she was upset by the aggressiveness of the police officers rounding up the demonstrators, the New York Daily News reported.
"I have never been afraid of an NY policeman until last nite. What I saw was random & senseless arrests and unnecessarily threatening behavior," she posted on Twitter.
Barkin, 57, was angry that she was ushered off the street by a police officer who pushed her by the shoulders, an incident caught on video by her companion, 26-year-old actor Sam Levinson, the Daily News said.
"Take your [expletive] hands off me," she can be heard saying.
In another tweet, she asked: "Is it a crime 2 stand in the street in NY? WTF is going on here?"
Police officials had no comment Sunday night, the newspaper said.
The arrests came as police shut down an Occupy Wall Street march near Union Square. Protesters in Zuccotti Park pulled down metal police barricades sealing off the public park.
