AKIPRESS.COM - A New York police officer was hurt and at least 100 people were arrested Wednesday as thousands of protestors gathered in support of Freddie Gray, the 25-year-old Baltimore black man who was fatally injured in police custody this month.

Demonstrators flooded open spaces around Union Square, chanting and holding signs protesting Gray's death from spinal injuries. His funeral was Monday, the day mostly peaceful protests in Baltimore turned into mayhem, with 20 police officers hurt, more than 200 arrested and buildings and cars set ablaze. The NYPD officer's injuries appeared minor.

The rally was organized by Millions March NYC, the group that rallied tens of thousands of New Yorkers to march on NYPD Headquarters in December to protest the police killings of unarmed blacks. A spokesperson for the organization said upwards of 3,500 people took part in Wednesday's protest.
