Shocking video shows a brawl at The Mall at Bay Plaza on Baychester Avenue.

In a now-viral video, around four to five people can be seen fighting and throwing what appears to be line divider poles often used at shopping malls during the holiday season for Santa meet-and-greets.

The video was posted to an Instagram account called @BronxAntics and has now amassed more than 1,000 comments.

The incident happened the night of Wednesday, Dec. 18 when many Bronx residents were doing last-minute shopping.

Sources close to the investigation tell News 12 that an 18-year-old man was arrested.

Repeated calls and emails to Prestige Properties, which owns Bay Plaza Mall, were not answered or returned.
