Violence broke out late Friday night outside Delaney Hall in Newark when state police tear gassed protestors.
Gov. Mikie Sherrill originally brought state police to prevent tensions from escalating between Immigration and Customs Enforcement (ICE) agents and protesters.
Designated protest zones and checkpoints were set up outside the immigration jail.
Police called the zones First Amendment zones, but many protestors resisted moving into the designated areas.
A News 12 crew that was on the scene said things took a turn around 11 p.m. when tensions boiled over.
The crew observed multiple flash bangs and pepper spray in the air and state police began to march toward the crowd.
Protestors and ICE agents have been clashing all week.
The protests started over a week ago after detainees inside launched a hunger strike over poor living conditions. But late Friday marked the first time in which state police became involved.
News 12 reached out to Sherrill's office for more information but was still waiting for a response as of Saturday morning.
