NEW YORK (CBSNewYork) – A group that supports the protesters in Baltimore gathered in Union Square Wednesday and shut down the outbound Holland Tunnel, the West Side Highway and several other city streets as they marched.

More than 100 protesters were arrested as officers clashed with protesters around Manhattan, CBS2 reported. The protests followed rioting that began in Baltimore on Monday, in response to the police custody death of Freddie Gray.

Several hundred people gathered in Union Square around 6 p.m., and during the 7 p.m. hour, about 200 people broke off from Union Square and marched down 17th Street despite an order by officers to stay off the streets, 1010 WINS’ Gary Baumgarten reported.

On 17th Street between Fifth and Sixth avenues, protesters marched for less than five minutes before coming face to face with a line of NYPD officers in riot gear – a barrier that sparked instant anger and countless clashes in the street.

No serious injuries were reported, but a commanding officer from the NYPD 13th Precinct suffered minor injuries when he was hit with a flying object near Union Square, police said.

There were too many arrests to track on the ground – some of them more dramatic than others, CBS2’s Weijia Jiang reported.

Jiang reported she and her crew got jostled around running in the middle of the action, and said the confrontation was more physical than those seen in Baltimore on Tuesday – the day after the riots.

Three officers were seen carrying one man, using every ounce of his energy to resist. Another handcuffed man was crouched in the street with his mouth gagged, and police also put several women into custody.

Still, hundreds of people stayed defiant and determined.

“They’re obstructing us,” one man said. “We would like to march. These are our streets.”

The man said it did not matter that police did not want protesters in the street.

“This is what justice is,” he said. “Sometimes it’s not pretty, but it has to happen.”

One woman said she was disappointed that police were arresting people for being in the street after being so accommodating in other protests.

As some protesters got into a shoving match with officers on 17th Street, and one woman ran in and shouted to stop, WCBS 880’s Alex Silverman reported.

“Please. We’re not here to fight with the police. That’s not what we do,” she said. “We make more noise when we don’t be violent.”

The protesters were of all ages and races with a shared voice, Silverman reported.

“A civilian who’s unarmed can just be murdered by a policeman,” the woman said. “It’s a terrible situation.”
