A convicted murderer who sent a violent death threat to Acting Immigration and Customs Enforcement (ICE) Director Todd Lyons has been arrested, the U.S. Department of Homeland Security announced Tuesday. Homeland Security Investigations (HSI) arrested U.S. citizen Daniel Barber in San Francisco on April 10, DHS reported in a statement recounting details of Barber’s email threat: “‘Your Gestapo Nazi maggot ICE agents should be terrified,’ Barber said in an email sent on June 6, 2025. He added that ICE law enforcement officers ‘deserve’ to be ‘executed right there as well with two f**king bullets to the back of their maggot Nazi heads!’ “Barber added, ‘And that is not a threat, you little f**king b*tch, but simply my opinion as to what those worms deserve. I’ll be f**king praying daily to the universe Americans start rising up and giving them, and you, exactly that.’” Barber has a lengthy criminal history, including a conviction for murder and robbery with intent to cause bodily harm in 1990. He also has multiple arrests for burglary, battery, and vehicle theft, DHS notes. “Comparing ICE day-in and day-out to the Nazi Gestapo, the Secret Police, and slave patrols has consequences,” Acting Assistant Secretary Lauren Bis said, explaining that sanctuary politicians have created an environment that encourages rampant assaults on law enforcement: “As our ICE law enforcement officers remove murderers, rapists, pedophiles, gang members, and terrorists from American communities, they are facing a more than 1,300% increase in assaults, an 8,000% increase in death threats, and a more than 3,300% increase in vehicle attacks.” Despite the surge in threats and assaults, ICE has remained undaunted in its work to enforce the nation’s immigration laws. “We are NOT afraid of you,” DHS declared in a warning to would-be attackers in a social media post last December following the arrest of twin brothers charged with making terroristic death threats to then-DHS Assistant Secretary for Public Affairs Tricia McLaughlin. “Let this be a warning to anyone who dares threaten or attack our law enforcement and DHS officials. We will find you, we will arrest you, and we will prosecute you to the fullest extent of the law,” DHS promised in the post.  “The violence and dehumanization of these men and women who are simply enforcing the law must stop,” Bis said.
