Baltimore police are investigating after a viral video appears to show a Baltimore Ravens fan attacking two Washington Commanders fans in Federal Hill.

The video was posted to social media on Sunday evening and has since been shared by multiple accounts. A post on X that shared the video received more than 13 million views as of Monday evening.

Police said Monday they were aware of the video but had not received any calls or reports related to the incident.

The Ravens defeated the Commanders 30-23 at M&T Bank on Sunday afternoon. The highly anticipated game, often referred to as the “Battle of the Beltway,” extended the Ravens’ winning streak to four games.

In the 20-second video, a man wearing a Lamar Jackson jersey approaches two men wearing Commanders jerseys outside the Cross Street Market on Charles Street. They appear to briefly make eye contact before the man in the Ravens jersey kicks and punches a Commanders fan and throws another into a wall. The man in the Ravens jersey then walks away and yells, “I’m not losing.”

The status of the two men wearing Commanders jerseys is unknown. It is unclear what sparked the altercation.

Federal Hill is a popular spot for restaurants and bars during and around Ravens games. While people are passionate about their sports teams, many online felt that this incident went too far. Some have called for the man in the Ravens jersey to be identified and arrested.

Baltimore police said anyone with information about the incident in the viral video can contact the Southern District at 410-396-2499 or Metro Crime Stoppers at 1-866-7LOCKUP.
