After violence erupted in an ICE detention facility, a message left on a window said, 'HELP US'

(CNN)Inside the ICE detention wing, the signs of clashes lingered hours after violence erupted and pepper spray was fired.

Mattresses had been flung onto the floor. Detainees' belongings were strewn across the room. A message that appeared to be scrawled in soap on a window simply said: "HELP US."
Weeks later, officials and lawyers representing detainees at the C. Carlos Carreiro Immigration Detention Center in Bristol County, Massachusetts, are still painting a starkly different picture of what unfolded that day. But they agree on one thing: The May 1 brawl began with a dispute over coronavirus testing.
      Multiple investigations into the incident are underway. And the American Civil Liberties Union of Massachusetts filed a lawsuit this week calling for the Bristol County Sheriff's Office, which runs the facility under an agreement with ICE, to release surveillance videos and other records. The sheriff's office says it will do so once investigations are completed.
        Immigrant rights advocates say regardless of what investigators uncover, the clashes earlier this month at this detention facility in Massachusetts exposed a dire situation that's unfolding across the country and growing worse by the day.
          Tensions over the coronavirus have been simmering in the sprawling network of US immigrant detention centers for months. But advocates say there are signs that fears of contagion are intensifying for the more than 26,000 detainees in ICE custody and the guards charged with protecting them -- and that tensions are boiling over.
          Advocacy groups say hunger strikes have been on the rise since concerns about Covid-19 surged. So have reports of incidents involving use of force, such as the pepper spray that officers fired at the Bristol County facility on May 1.
          "It's a huge increase. ... This is a trend," said Silky Shah, executive director of the Detention Watch Network, which is pushing to end immigrant detention in the United States and regularly tracks reports of hunger strikes and other incidents at ICE facilities as part of its advocacy efforts.
          "This is what ICE detention is. And it's not unique to any one facility. In so many different places, we're seeing similar procedures and practices."

          How clashes over coronavirus testing erupted at one facility

          Bristol County Sheriff Thomas Hodgson said officials had no choice but to deploy a K-9 unit and pepper spray that day.
          A group of 25 detainees in one wing of the detention center became violent and trashed the unit, he said, after officials told 10 of them they had to report to the medical unit for coronavirus testing. At one point, Hodgson said detainees rushed toward him and one hit him with a chair.
          "They destroyed the taxpayers' facility. They were obviously poised. ... What they did to this unit, you're going to be shocked," Hodgson told reporters before giving a tour of the damage the next day. His office said more than $25,000 in damage was done before officers quelled the violence.

          No officers were injured, according to officials, but three detainees were taken to a hospital.
          ICE praised the sheriff's office, saying officials had "responded rapidly and professionally to de-escalate a volatile situation, limiting injuries and further damage to the facility."
          The use of pepper spray was consistent with the agency's protocols, ICE said, and allowed staff to restore order.
          "During the incident, the detainees caused severe damage to jail property, breaking windows, washing machines and causing other property damage," ICE said.
          But lawyers representing detainees accuse the sheriff and his deputies of inciting the violence in retaliation for a pending class-action lawsuit that alleges overcrowding and inhumane conditions at the center.
          "Our clients have all consistently and credibly indicated that the sheriff incited this incident, and that the sheriff violently responded to legitimate requests for Covid-19 testing, and to legitimate fear surrounding how or where they were going to be tested," said Iván Espinoza-Madrigal, executive director of Lawyers for Civil Rights.
          Detainees wanted to be tested for coronavirus, but didn't want to be taken to the facility's medical unit, located in another building, because they feared they'd run a further risk of infection, Espinoza-Madrigal said.
          A spokesman for the sheriff's office told CNN claims of retaliation are "absurd," adding that the sheriff hadn't touched a can of pepper spray in decades.
          "I assure you no staff member is responsible for the incident. Our staff acted professionally and appropriately, and any independent investigation into the incident will find the same thing," spokesman Jonathan Darling said. "It's all a misinformation campaign by political groups who are doing all they can to promote their anti-ICE, pro-illegal immigrant, anti-law enforcement agenda."

          It's not the only place where pepper spray has been deployed

          Other recent incidents involving use of force have been reported at several facilities across the country, according to Freedom for Immigrants, an advocacy group that tracks conditions in ICE detention through reports from detainees that call its hotline.
          "As people inside their custody raise legitimate concerns and demands over their health," the organization said in a recent memo outlining reported conditions, "ICE and prison officials continue to respond with retaliation and abuse, meeting expressions of concern regarding the spread of COVID-19 inside detention with use of force."
          ICE says the agency has taken additional steps to safeguard detainees in response to the coronavirus pandemic and maintains that providing medical care to those in its custody is a top priority. The agency has said it released more than 900 detainees who it determined "might be at higher risk for severe illness as a result of Covid-19" in recent months and continues to evaluate release on a case-by-case basis.
          So far, more than 1,100 ICE detainees have tested positive for coronavirus, according to the latest statistics on the agency's website.
          Detainees lay on their bunks in their pod at the Stewart Detention Center in Lumpkin, Georgia, on November 15, 2019.
          Asked about reports of increasing incidents involving use of force such as pepper spray, an ICE spokeswoman said the agency had not compiled national statistics on such incidents.
          "When detainees become confrontational, destructive or unsafe, and attempts to deescalate a situation are unsuccessful, the use of OC spray by detention center staff is authorized and consistent with agency protocols, to preserve order and protect the safety of everyone in detention," spokeswoman Danielle Bennett said in an emailed statement.
          At the Stewart Detention Center in south Georgia, one of the largest immigrant detention centers in the country, pepper spray was deployed at least twice last month.
          The altercations, first reported by The Intercept and WNYC Studios' The Takeaway, reportedly involved a SWAT-like team at the facility known as the Special Operations Response Team, or SORT.
          In both instances, according to ICE, pepper spray was used because detainees had become "disruptive and confrontational with facility staff."
          "This calculated use of force was conducted consistent with agency protocol," ICE said. "Medical staff evaluated all individuals who came in contact with the pepper spray; no detainee or staff injuries were reported."
          CoreCivic, the private prison company which operates the detention center, said its staff adhered to ICE's standards regarding use of force.
          Staff at Stewart quelled a protest on April 9 after detainees "blocked the pod door, covered the windows and refused to return to their beds," CoreCivic spokeswoman Amanda Gilchrist said. On April 20, she said, "staff responded to a protest in a housing unit that was initiated by a group of detainees who became disruptive, creating hazards to block the door and refusing to comply with verbal directives provided by staff."
