The 23-year-old has left Real on a high note after he has spent several seasons with the club, mainly featuring as a forward and a wingback.
Mbemba, fondly called Daddy, has won two First Division titles with Real de Banjul, two Super Cups and was instrumental in the club’s success against FUS de Rabat in the CAF Champions League in 2013.
President William Abraham said: “As everyone knows, Mbemba Colley’s achievements have been nothing short of fantastic. Everyone at the club is indebted for all he has done and our sincere best wishes go with him. He will always receive a warm welcome at this club.”
He added: “He has been a leader for the club on and off the pitch and we are sad to see him go. But everyone at this club wishes him all the best for his career in the future.”
