Luxury stores in the mall ain't safe anymore.

Earlier this year, DaBaby knocked out a rival in Louis Vuitton shop in a North Carolina.

Now we have video of PnB Rock and his PnB crew of at least five deep busting into a Neiman Marcus in the King Of Prussia mall outside Rock's hometown of Philly and giving three men a wild beating.

Eyewitnesses say PnB and his boys rolled up to the mall in Escalade, jumped their victims as they were shopping, and then left. The police didn't get involved.

Earlier that day, PnB and his goons were hanging out in the Hill Creek projects in Philly.

Rock has been arrested twice this year.  First on drug and stolen firearm charges in Pennsylvania, and earlier this month in Watts.
