The vice-president of policy think tank, IMANI Ghana, has said claimed the efforts may be underway to rig the 2016 presidential election in favour of the National Democratic Congress (NDC).
In a Facebook post on Friday, he challenged the Electoral Commission's statement that the turnout for voting in the constituencies collated so far was 49%.
Bentil said it was impossible for the voter turnout to be 49%, saying that the EC had lied.
He speculated that there is an ongoing attempt to subvert the will of the people.
He ended by urging members of the public to stay alert.
It comes after several media networks in Ghana projected Nana Akufo-Addo as the winner of the 2016 election.
Joy FM's latest collation data, based on 220 constituencies, has Akufo-Addo leading by 53.48%. Mahama has 44.69%. It is said to be statistically impossible for John Mahama of the NDC to catch up.
