BEAUMONT, TEXAS — This is an official press release from the U.S. Department of Justice (USAO - Texas, Eastern), published as received.

BEAUMONT, Texas – Two illegal aliens have been indicted for assaulting federal employees at a detention facility in the Eastern District of Texas, announced U.S. Attorney Jay R. Combs.

The assaults are alleged to have occurred at the IAH Polk Adult Detention Facility in Livingston where both individuals were being held pending their removal from the United States.

Andrei Siskov, 41, a Russian national illegally in the United States, was indicted by a federal grand jury this week and charged with assaulting or impeding federal officers.  The two-count indictment alleges that on February 22, 2026, and again on April 4, 2026, Siskov assaulted detention officers who were contract employees of the Department of Homeland Security.  On February 22, Siskov spit a mouthful of saliva in the face of a detention officer. On April 4, Siskov punched a detention officer in the face causing injury to the officer and leaving visible marks. Siskov faces up to 20 years in federal prison if convicted.

Rosbin Melgar-Lopez, 31, a Guatemalan national illegally in the United States, was indicted by a federal grand jury and charged with assaulting or impeding a federal officer.  The indictment alleges that on March 19, 2026, Melgar assaulted a Department of Homeland Security deportation officer.  On that date, Melgar bit a detention officer on the forearm causing injury. Melgar faces up to 20 years in federal prison if convicted.

These cases are part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, to achieve the total elimination of cartels and transnational criminal organizations (TCOs), and to protect our communities from the perpetrators of violent crime.

These cases are being investigated by the Department of Homeland Security and prosecuted by Assistant U.S. Attorney Lauren Gaston.

A federal indictment is not evidence of guilt.  All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
