Rapper 2 Chainz received an unwelcome Christmas present on Tuesday (24Dec13) when he was formally charged for obstruction of justice relating to a police run-in in August (13). The I'm Different hitmaker, real name Tauheed Epps, was busted alongside members of his entourage over the summer (13) after refusing to let an officer onboard his tour bus to investigate the smell of marijuana smoke emanating from the vehicle. The cop, who had initially stopped the bus due to a faulty tail light, booked 11 people for obstructing a police officer, and now 2 Chainz has been officially charged with the misdemeanour. Taking to his Twitter.com page on Christmas Eve (24Dec13), he wrote, "So the fact that OKC (Oklahoma police) is charging me with obstruction months after pulling my bus over And finding nothing lets me know the devil is busy". If convicted, he faces up to a year behind bars and a $1,000 (£670) fine, reports AllHipHop.com. 2 Chainz spoke out about the arrest in September (13), insisting he had done nothing wrong and accusing police of unfairly targeting him. He told MTV's RapFix Live show, "You're not gonna find a kilo on my bus. You're not gonna find an unregistered reason. I went to work all last year. I paid taxes. I did everything I was supposed to do. So maybe people need to start aiming at some criminals. For me, I'm cold turkey on all criminal activities. I don't wanna do anything criminal. It's just about wasting your time, my time and taxpayers' money."
