Early Sunday morning Fetty Wap had his chain snatched at a deli in his hometown of Paterson, NJ. That sparked a shootout which left three men with non-life threatening injuries.

Afterward, Raheem "Fuzz" Thomas -- who has a beef with Fetty over music deals -- showed the chain off on social media.

Not long after the stunt, Fuzz was arrested for aggravated assault and multiple gun possession charges.

TMZ has obtained video of the incident.

In it, you see Fetty and Fuzz's crew brawling in the middle of the aisle. While it doesn't capture the gunfight, you can see Fuzz holding a firearm.

TMZ has learned that Fetty almost always comes into the all-night deli after partying on Saturday, so Fuzz would have known where to find him.
