According to him, the PDP candidate scored 87,609 to win the election while his closest rival, Hon Muhammad Alkali of the PRP polled 67, 331.
The PUNCH reports that the announcement of the winners for Plateau North senatorial election and that of the Bassa/Jos North Federal Constituency was originally meant to be announced at the Jos North Local Government Secretariat, where the Collation Center for the two elections was situated.
However, there was tension at the secretariat over the invasion of the collation center by thugs alleged to be loyal to the PRP candidates.
The thugs had earlier chased the INEC officials out of the collation centre, a development which made the electoral body move the centre to another location.
The election results were announced in the Tudun Wada community of the state.
