“Such a loss, at a time when the party was building bridges of unity is disheartening.”
Mr Mahama lost his life a few hours after an acid attack on him Wednesday night.
Two suspects have been arrested. One is said to be a brother to Mr Afoko.
This has fuelled speculations that the attack may have been as a result of last week’s “commotion” – as described by the deceased later – in the Region when Mr Afoko and General Secretary Kwabena Agyepong attempted to meet some constituency executives.
“I have championed a cause of unity in the party; consistently, I have urged party faithful to avoid divisions. Discernibly who stands to gain from such divisions, tragedies and tensions?” Mr Afoko wondered in a statement on Thursday.
He described the loss as “a very big blow to both his family and the party.
“Irrespective of whatever differences some may have had with him, Adams was a stalwart in the party in the region,” he added.
“Indeed, these are sad moments for us all.”
Mr Afoko has endorsed full-scale investigations into the death, recommending that: “Whoever was responsible must be made to face the full rigours of the law.”
Mr Mahama is expected to be buried on Friday as Islamic customs demand.
