Benson said police told them that someone had written a bogus check previously.
"They thought I did it too, but I'm legit," Benson said. "They confused me with whoever they were looking for."
Benson said police apologized. He said police initially took $100,000 of his cash, but later said that he had gotten that money back.
The rapper said he had withdrawn the cash to buy a vehicle. Initially, Benson said he was in the market for a Maybach, but after the incident at the bank, he said he was thinking about a Ferrari.
"I'm feeling fast," Benson said.
