New Haven police say they are preparing for a significant turnout Sunday on the New Haven Green for a planned protest that is being described as Connecticut's largest pro-Palestinian demonstration.

Police are expecting a large but peaceful crowd.

"We're used to this kind of thing in New Haven, we have a lot of protests and gatherings. We expect it to be peaceful. We have extra officers coming in, we have some motorcycles that are going to be in the area. We are prepared for any eventuality." says Officer Christian Bruckhart.

Organizers say they are expecting a massive turnout.

Over 20 groups from around the state are believed to be participating, including student organizations from Yale and UConn.

Rallies were held at both schools this week. During Monday's rally on Yale's campus, more than 40 were arrested by campus police.

"The New Haven Police Department didn't make any arrests on Monday. We had some negotiations with the organizers of the protest, and thankfully they decided to get out of the street and allow traffic to flow normally," says Bruckhart.

Police do not expect the protest to resemble any recent protests happening on college campuses, including the one at Yale.

Bruckhart says there are no road closures planned for Sunday as the protest is set to take place entirely on the Green.

"The New Haven Police Department strongly supports the First Amendment and people's exercise of free speech. If they start going into the road or if there's any indication of threats or violence, that's when we'd be more likely to take enforcement action," he says.

As the school year winds down, police expect fewer student led protests.

"Once they go home for the summer, I wouldn't anticipate the student-type protests, but again, that might evolve into something else. We have no indication that there's anything other than peaceful and nonviolent, and we hope it stays that way," says Bruckhart.
