May 31 (UPI) — Newark, N.J., Mayor Ras J. Baraka instituted a curfew early Sunday in the area around an immigration detention facility where protesters have gathered in reaction to a hunger and labor strike there.

Baraka’s announcement came amid growing conflict between those supporting the hunger strikers at Delaney Hall detention facility and those who support the Trump administration’s immigration crackdown. The strike has been in effect since May 22 with detainees protesting what they describe as inhumane conditions at the facility.

Supporters of the strikers have gathered outside the facility since the start of the strike, and some have gotten into scuffles with Immigration and Customs Enforcement officials, prompting anti-immigration protesters to join the demonstrations.

“Due to the escalating situation at Delaney Hall and the increasing need for police intervention, immediate action is required to protect public safety,” Baraka said in a statement. “Multiple individuals have already been arrested and found in possession of weapons, underscoring the seriousness of the threat.”

Baraka said the curfew went into effect at midnight and applied to a half-mile surrounding the facility. He closed Doremus Avenue to all pedestrian traffic and limited vehicle traffic to those with official business in the area.

“This curfew will remain in effect nightly from 9 p.m. to 6 a.m. until further notice,” the mayor said.

In his statement, he said those violating the curfew will be issued a warning, and non-compliance would “result in removal from the area and the issuance of appropriate summonses and/or further legal action.”
