Occupy Wall Street protesters rallied in New York City's Grand Central Terminal to call attention to a law signed by President Barack Obama that they say could curb civil liberties.
The protesters gathered in the main concourse of the station Tuesday where they held a noisy rally as hundreds of commuters rushed by.
Twitter reports indicate approximately three arrests related to the Grand Central rally.
Obama signed the National Defense Authorization Act into law on New Year's Eve. Civil rights groups have criticized provisions in the bill that they say seem to grant the military extraordinary powers to detain U.S. citizens indefinitely without trial.
The protesters held a series of actions Tuesday designed to call attention to the law.
