The 22-year-old tested positive for banned substances Prednisolone and Prednisone in Dormaa Ahenkro and did not travel with the squad for the return fixture in Kinshasa.
The youngster was impressive in his side’s 2-1 home win which prompted suspicions of Caf’s medical team.
However, he pleads not guilty, maintaining that he went for a 'pain killer' at a pharmacy.
"I went to the pharmacy before the first leg to purchase a drug after complaining of pains in my chest and thigh so I didn't know they were part of the banned substances," Anokye told Goal.
"I even took the drug with our midfielder Elvis Opoku because he was also having similar problems. I don't rely on drugs for strength so I was surprised when they said I've tested positive.
"Throughout my career, I've never engaged in doping so I believe I was misled at this point. If I knew the consequences, I wouldn't have taken the drug so I'm wrong but it was not my fault," he added.
Goal understands that Aduana have officially written to Caf to explain the situation but it's likely Anokye Badu will serve at least three months suspension.
