New details have emerged in the Paterson, New Jersey all-night deli shooting involving Fetty Wap.

Eyewitnesses tell TMZ that the rapper and his team were followed into the deli by longtime rival Raheem "Fuzz" Thomas and his Muscle Team crew. Fuzz pistol whipped one of Fetty's boys, a fight ensued, and Fetty's chain got stolen.

After that, someone from Wap's team pulled out a gun and fired shots, hitting two members of the Muscle Team. In the gunfight that ensued, Fetty's original shooter Cheddar Bob-ed himself in the leg.

Fuzz was arrested after the incident and charged with gun possession and assault.  But police now say they don't believe Fuzz fired shots.

Fetty has yet to speak out about any of this, and is refusing to cooperate with police.

He is said to have lost $450,000 in jewelry and thousands in cash in the incident.
