Family visitation at the Delaney Hall immigration detention center is being restored to at least part of the facility, New Jersey’s governor and US homeland security officials confirmed on Sunday morning, after a week during which heated demonstrations at the site were met with aggressive policing tactics.

Meanwhile, families of detained immigrants grappled with conflicting information about exactly whom among them would get visitation after the announcement from governor Mikie Sherrill and the US Department of Homeland Security (DHS). And local officials by Sunday had also indefinitely imposed an overnight curfew beginning at 9pm for a blocked-off area including Delaney Hall.

Delaney Hall visitation had been canceled after detained immigrants began carrying out an ongoing hunger and labor strike inside the detention center – which prompted protests outside the facility in support of those striking.

Facility staff confirmed to the Guardian on Sunday that what are known as units 1 and 3 were given visitation beginning at about noon and 2pm local time, respectively.

Unit 1 is a women’s section of the facility. Unit 2 is where the majority of the hunger-striking detainees are based, and it was unclear on Sunday whether it would have access to family visitation.

Sherrill’s office and the private prison company GEO Group, which runs the facility, did not respond to a request for comment. The road leading to Delaney Hall is now fully blocked by police, except for families attempting to visit detained loved ones, state officials announced on Sunday afternoon.

The governor’s announcement and subsequent confusion by families followed a night of violent clashes outside the facility between local officials and protesters. In the aftermath of that, Newark’s mayor, Ras Baraka, responded by activating a curfew for the area surrounding Delaney Hall.

The curfew would be in place nightly from 9pm to 6am “until further notice”, said Baraka’s office, which threatened arrest or legal action if people did not disperse during that time.

On Sunday morning, Sherrill and other top New Jersey state officials said that three people were arrested on Saturday night as a result of clashes with police. State officials said those arrest happened after a group of protesters attacked police and a barrier.

The Delaney Hall protests and clashes have become the latest flashpoint in the growing opposition to the aggressive anti-immigrant tactics Donald Trump’s administration has implemented nationwide throughout his second presidency.

Immigration and Customs Enforcement (ICE) detains immigrants in its network of facilities across the US while the cases of those detained play out in courts.

ICE detention centers have been repeatedly criticized for harsh conditions.

Hakeem Jeffries, the top US House Democrat of nearby New York, conducted an oversight visit of Delaney Hall on Sunday, and said the conditions of confinement “shock the conscience”.

On 22 May, a group of immigrants detained inside Delaney Hall detention announced a hunger and labor strike inside the facility, demanding improved conditions, medical care, a meeting with Sherrill and for their immigration cases to proceed. Between 300 and 400 detainees have since participated in the strike.

Protests began shortly thereafter, with lawmakers attempting to visit the facility. The facility gained further national attention after ICE officers pepper-sprayed US senator Andy Kim, a New Jersey Democrat, outside the facility during a skirmish there on Monday.

ICE officers have used pepper spray as well as stun guns throughout the demonstrations. They have also shoved and arrested protesters.

On Friday, Sherrill and other top New Jersey officials announced that state police would replace ICE officers outside Delaney Hall. The state police set up road blocks around half a mile on either side of the detention center.

That night clashes erupted after state police officers began moving in on protesters. State police officials on horseback moved through the crowd. Other state police officers in riot gear shot teargas canisters at protesters, aggressively shoving demonstrators and arresting six.

Advocates present at Delaney Hall on Saturday repeatedly criticized Sherrill, a Democrat, for her response to the protests.

“The escalation that happened [on Friday] was ten times worse than what ICE was doing to everyone prior nights,” Murad Awawdeh, the president and CEO of the New York Immigrant Coalition, said in an interview on Saturday outside of the facility. “If anything, the escalators were the state police.”

A statement from Sherill on Saturday announcing the restoration of family visitation at Delaney Hall claimed DHS had “met our demand”. But DHS refuted the governor’s statement.

“To be clear: Visitation was only suspended because of violent riots,” a DHS spokesperson said. “Now that we have a secure perimeter, visitation can resume.”
