The chairman was returning from his construction site late in the night when the two unknown men stopped him.
They immediately poured acid on him while in his vehicle close to his residence, the Upper East regional police command confirmed to Starrfmonline.com.
The regional chairman was rushed to the Bolgatanga Regional Hospital where he is currently being treated.
According to his aide Zakaria Osman, his boss is battling for his life because the corrosive substance has damaged his face.
Adam has been in the news recently after some irate supporters of the Danquah-Busia-Dombo tradition chased out the party’s national chairman Paul Afoko and general secretary Kwabena Agyepong from a meeting in the region.
The incensed party members allegedly attacked the national executives and others with sticks and broken bottles for organising the meeting without informing the regional chairman Adam.
The timely intervention of the police prevented a bloodbath.
Adam, who was accused as the mastermind of the melee, later apologised but cautioned national executives to respect party structures.
He said in the statement: “This unfortunate development was entirely avoidable. It has brought to the fore two urgent matters which have to be rectified as soon as possible and the elected National Officers of the Party must be proactive in doing so.
“Firstly, I am appealing to the National Chairman and General Secretary to stop this habit of sidelining elected officers they do not like. They must respect the structures of the party and work with the structures and hierarchy of the Party, including their colleagues at the Headquarters and the Regional Chairman across the country. The more they seek to sideline those the Party Constitution says they must work with the more suspicion and problems they fuel in the NPP.
“It was wrong for them to go on a region to region campaign without consulting the regional chairmen of the first two regions they visited. We want them to consult the leadership of the party in the various regions and not to sideline existing structures of communication and operation in the running of the party at the regional level."
He added: “A case in point is the fact that I, as Regional Chairman of the Upper East, was in Accra the whole of this week until yesterday, and in fact boarded a morning flight to Tamale just like Chairman Afoko and Kwabena Agyepong, on Thursday. In fact they were well aware of my presence in Accra as I had been to the National headquarters on several occasions during this week, and yet they chose not to inform me about their intention to visit my region. They rather chose to consult and work with some constituency and regional executives. This is not helpful, especially at a time when we want to build unity at the leadership level.
“Secondly, I urge the National Chairman and the General Secretary to stop their preferred mode of operation, which is to sideline the other elected National Officers in decision making at the top. It is only fuelling flames of suspicion and I urge them to stop this and begin working with the rest of the team. After what happened at the last Steering Committee, the rank and file of the party want to see the National Officers working together.
Would it not have been nice if the Chairman and the General Secretary had chosen to go on this trip of the regions with the other National Officers to show unity? If they want to be believed that they mean well then they should let us see that they are prepared to work with the other elected National Officers. The Chairman and General Secretary should not be seen to be trying to run a two-man show, and by that marginalise the other executives. They should be seen travelling and working with the other national officers to show a united front to the members of the party.
“The delegates in Tamale, last year, elected National Officers on the same day and charged them to work together, and that is what the rank and file want to see. We at the regions are willing and ready to work with all of them but we shall not tolerate anybody who wants to be an impediment in the route to victory in 2016.”
