Fetty Wap is in trouble with the feds.

The “Trap Queen” rapper was arrested at Rolling Loud New York on Thursday (Oct. 28). Prior to his performance at Citi Field, he was taken into custody by the FBI.

According to legal documents, obtained by TMZ, Fetty is accused of distributing more than 100 kilograms of cocaine, heroin, fentanyl, and crack cocaine across Long Island and New Jersey. The feds claim the drugs were first obtained on the West Coast and were smuggled to the East Coast via USPS vehicles with secret compartments.

During the investigation, the feds obtained $1.5 million in cash, 16 kilograms of cocaine, 2 kilograms of heroin, fentanyl pills, pistols, handguns, and a rifle.

If convicted, Fetty and his co-defendants could face life in prison.

Fetty has remained out of the spotlight for most of the year. Last week, he returned from his musical hiatus with his new project The Butterfly Effect.
