ORLANDO, Florida (CMC) — The United States Immigration and Custom Enforcement (ICE) agency said an undocumented Jamaican has been indicted in Florida on multiple felony charges for assault on a US federal official, as well as being an illegal immigrant in possession of a firearm.

ICE said the charges follow an investigation by its Enforcement and Removal Operations (ERO), the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the Orange County Sheriff’s Office.According to court documents, Oniel Christopher Russell, also known as OG Russell, 39, threatened to kill an employee of US Citizenship and Immigration Services (USCIS) by phone in October 2016 after posting a video of himself called “cop killer” on YouTube.Prior to this incident, ICE said Russell had been found in possession of a Ruger firearm by deputies with the Orange County Sheriff’s Office in August 2013 — it is a felony for an illegally foreign national to possess a firearm.The ICE said the deportation officers subsequently executed an administrative arrest warrant for Russell on immigration charges on April 25, during which Russell resisted arrest in an attempt to flee by dragging a deportation officer into a wall who was attempting to handcuff him.Russell was eventually taken into custody. If convicted on all counts, he faces a maximum penalty of 18 years in federal prison.ICE also said it has filed an immigration detainer against Russell and will seek to take him into custody to place him into removal proceedings following the resolution of the criminal charges he presently faces.
