The 35-year-old performer, born Tauheed Epps, was apparently uncooperative when police arrived at the scene, hoping to handle the situation himself.
Police told MTV News that the perpetrators had stolen the rapper's wallet "containing credit cards, U.S. currency and a cell phone."
In several cryptic tweets, 2 Chainz appeared to deny reports that he had been robbed.
