He was also accused of evading police charges. The messages allegedly detailed a conversation between B.I and the dealer, in which the singer asked for a bulk discount and the dealer warned him about the effects of taking drugs. He posted a letter on his personal Instagram account revealing that the messages were true and explained that he was going "through a hard and painful time" and wanted something to rely on.
