Four individuals sustained injuries during the incident, with two treated and discharged, while the remaining two are still receiving medical care.
In a statement, the police said they "have been actively working on the case throughout Sunday night when the incident happened and are closing in on the perpetrator to get him arrested to face justice." Reports indicate that supporters of Chris Arthur, a parliamentary candidate, were returning to Agona Swedru from a campaign launch in Otinkorang, a community in the Agona West area.
Along the way, they encountered supporters of incumbent MP Cynthia Morrison at Agona Nyankrom, who were also campaigning.
As they passed through the crowd, a gun was unexpectedly discharged, injuring Haruna Rashid, Chris Arthur's campaign team manager, who sustained gunshot wounds to the ribs.
