Protesters in the city used Friday's annual May Day march to also protest Freddie Gray's death in Baltimore.
The march started around 6 p.m. at Union Square, then continued into Lower Manhattan. That's where things got tense between police and protestors. They wanted to visit a public housing complex, but police wouldn't let them deviate from the approved route.
"We have a right to visit our friends in the projects," said one protester. "They're trying to direct us off and send us back in a circle back to Union Square."
"Our route is changed. We want to go this way," said another. "These are, like, artificial. What does it matter that we have these barricades here? The community is this way. We have every right to go this way."
Police Commissioner William Bratton said the NYPD is willing to work with protestors, as long as they follow the law.
Demonstrations earlier in the week netted more than 100 arrests.
