According to a report by Kumasi-based Angel FM, Amadu was asked not to return to the team after the Club had confirmed parting ways with team manager Shilla Alhassan.
Kotoko prior to the latest decision had sacked assistant Coach Michael Osei and head Coach Zdarvsko Lugarosic who took charge of the team for just three months.
Further reports also indicate a member of the communication team Thomas Boakye-Agyemang has also been relieved from his duties.
Kotoko’s recent indecisions is believed to be as a result of the team’s poor run in the League leaving most of the Club’s fans worried.
