Police in Ghana have arrested more than 100 people – mostly opposition supporters of President-elect John Mahama – over acts of lawlessness.

Supporters of the newly elected president who want jobs have allegedly attacked some state institutions, looted properties, and engaged in disturbances that have left some police and military personnel injured.

The irate supporters also torched two electoral commission offices due to a delay in announcing the outcome of Saturday’s elections and disagreements over some parliamentary results.

Mahama has condemned the vandalism and called on President Nana Akufo-Addo and security agencies to “act decisively” in addressing the violence.
