A fitness influencer who rose to fame for his bizarre eating habits was arrested Tuesday after allegedly posting threatening messages aimed at podcaster Joe Rogan in a multi-video Instagram rant, according to authorities. 

Brian Johnson, a popular social media fitness influencer known as “Liver King,” was taken into custody by the Austin Police Department in a dramatic caught-on-camera arrest posted to his own Instagram page, police said. 

Detectives were notified of a series of alleged online threats made by Johnson against Rogan, and subsequently learned Johnson was traveling to Rogan’s hometown of Austin while continuing to make the alleged threatening statements, according to authorities.

Johnson, who boasts a whopping 2.9 million followers on Instagram, frequently posts about his self-described “ancestral lifestyle” and fitness routines, often sharing videos dedicated to his diet consisting primarily of raw meat. 

Rogan previously discussed Johnson’s alleged use of steroids on a 2023 episode of his podcast, with Johnson initially denying the claims before issuing an apology to his viewers. 

Johnson was charged with allegedly making a terroristic threat and transported to the Travis County Jail, according to APD. 

Representatives for both Rogan and Johnson did not immediately respond to Fox News Digital’s requests for comment.
