Police in Jacksonville are investigating a night of violence that included a rampage by more than 300 teenagers in a Walmart store.

A video shows young people pouring into the store, yelling, screaming and throwing merchandise. A security scanner worth $1,500 was destroyed.

The police did say that a few gunshots were fired outside of the store, but no one was reported injured.

This type of destructive mob violence has been popping up in Walmart stores in Florida and Oregon lately.

The worst part are the kids caught on camera bragging about how much they have stolen.
