At least a dozen people have been arrested on disorderly charges during a New York City rally protesting the acquittal of George Zimmerman.

Over a thousand people gathered in Manhattan’s Times Square Sunday to protest the Florida verdict that found Zimmerman not guilty in the death of unarmed black teenager Trayvon Martin.

The NYPD says between 12 and 20 people were issued summonses. An exact figure was expected later Monday.

The protesters first gathered in Union Square for a rally dubbed “Hoodies Up for Trayvon.” They hoisted placards bearing Martin’s picture and chanted “Justice for! Trayvon Martin!”

The marchers made their way to Times Square where they blocked traffic for more than an hour before moving on.

The case has unleashed a national debate over racial profiling and self-defense.
