Baltimore police have issued an arrest warrant for John Callis, a Ravens fan, after he was caught on video assaulting two Washington Commanders fans following a Ravens game victory. The viral footage shows Callis, wearing a Lamar Jackson jersey, attacking the Commanders fans unprovoked, kicking one and punching another, before flexing to the camera and proclaiming, 'I don't lose.' Callis, who was previously employed by Maury Donnelly & Parr, Inc., has been fired due to the incident and charged with first-degree aggravated assault and three counts of second-degree assault. Despite the assault, police report that no official complaints have been made, though they are actively investigating the situation. The Ravens had just secured a 30-23 win over the Commanders, marking their fourth consecutive victory and moving them to a 4-2 record.
