A Florida attorney was arrested after she threatened to shoot ICE agents in the head while trying to buy a gun, federal authorities said.

Lisa White, who lives in Mississippi, was arrested in Long Beach after allegedly threatening to "kill federal agents" while attempting to purchase a firearm and pepper spray, according to a U.S. Immigration and Customs Enforcement release.

HSI Gulfport special agents responded, interviewed witnesses and located and arrested White, according to the release.

The investigation began Sept. 23 after an agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives alerted HSI to the encounter at High Caliber Guns, according to a criminal complaint obtained by Threats against federal law enforcement will NOT be tolerated," HSI wrote on X. "HSI will continue to investigate threats against the brave men and women who put their lives on the line every day to protect our homeland."

The arrest comes as ICE reports a sharp increase in threats and attacks against its personnel.

In its release, the agency cited an increase of more than 1,600% in assaults, 3,300% in vehicle attacks and 8,000% in death threats against ICE officers. It did not provide the underlying totals or comparison period.

ICE said President Donald Trump and Homeland Security Secretary Markwayne Mullin have made clear that violence against law enforcement will not be tolerated, warning that people who threaten or attack officers face arrest and prosecution.

Fox News Digital reached out to White for comment.
