The robber, who were armed with an AK-47 assault rifle and a shot gun, shot 40-year old Antwi Boateng on the forehead and the right armpit after storming the bank on a motorbike, a report by adomfmonline said.
He was later pronounced dead at the Mampong Government Hospital. He is said to have left behind a wife and four children.
The robbers are said to have fired sporadically when they arrived at the bank, forcing many people to run for cover.
The Kwamang police, according to the report, said they received distress calls of the robbery incident and responded swiftly, but the robbers had escaped on their motor bikes by the time they got there.
The Mampong Divisional Command has mounted a search for the robbers after picking up information they abandoned their motorbike in the area, the report added.
