Fox News embedded exclusively with Immigration and Customs Enforcement (ICE) in the greater Boston area this week, when agents were carrying out the arrests of hundreds of egregious criminal migrants in what the agency said is the largest operation it has undertaken since President Donald Trump returned to office.

The sweeping operation is expected to net hundreds of arrests and is targeting immigrants like a Salvadoran illegal immigrant convicted of child rape who went to prison and was deported in 2017. He was nabbed by ICE living right next to a children’s playground.

ICE also swooped on another illegal migrant who is on El Salvador’s most wanted list and has an Interpol Red Notice for aggravated murder, aggravated kidnapping and robbery.

Both arrests were captured exclusively on camera by Fox News, with ICE Boston telling Fox News that local anti-ICE activists have been interfering in their operations this week. 

ICE deployed dozens of teams across Massachusetts this week, and the agency brought in ICE teams from other parts of the country to assist.

Patricia Hyde, the head of ICE Boston, said it is not uncommon to see immigrants convicted of child rape roaming public streets close to where children play. 

"It's not unusual. Due to the open border policies, we are finding that plenty of people who have been previously deported and committed heinous crimes and were removed from the country are now back here, just living among us," Hyde said. "And now that's our job to go round them up."

Fox News also joined ICE as they arrested a Colombian illegal immigrant facing pending charges for sexual assault of a child, as well as a Dominican illegal immigrant with a drug trafficking conviction who is now facing local charges for fentanyl distribution. 

Meanwhile, other arrests included a Guatemalan illegal immigrant who's facing charges in Massachusetts for aggravated child rape but was released from state custody. They also arrested a Honduran immigrant who is facing local charges for rape and was also released from local custody.

Hyde said sanctuary jurisdictions are starting to escalate against ICE. 

On Thursday, activists tried to grab onto an illegal immigrant who had been handcuffed by ICE. In another incident, agents were staking out an illegal immigrant murderer's home and a crowd gathered and blew their cover.

"I think the lack of cooperation is getting worse and worse, and it’s putting law enforcement lives in danger," Hyde said.

Hyde said that ICE agents will continue to round up dangerous criminal illegal migrants, despite pushback from local lawmakers and activists.  

"We're not going away. It might take us longer. It might be harder, but we're not going away, we're here," Hyde said. "We know what the American people voted for. We understand that we work for the American people and we're going to be here until we send everyone home."
