A brawl this past weekend on the CTA Red Line was captured on video.

The Chicago Transit Authority said the brawl happened around 7 p.m. Sunday at the Roosevelt station in the Soth Loop.

The video shows what appears to be a group of teens throwing punches and fighting.

The CTA did not comment on any security issues – only saying there was police activity, and trains bypassed the station for a short time.

The video shows security with K-9s responding, but Chicago Police said they have no information on the incident.

There was no word late Monday on whether anyone was hurt.
