At a press briefing in Kumasi, DCOP Augustine Gyening, Ashanti Regional Police Commander, told newsmen the police also arrested Mohammed Awal, 21, and Mohammed Yussif, 25 for wielding machetes and attempted murder at Aboabo post office area in Kumasi.
DCOP Gyening said the suspects were among scores of criminals that are members of a robbery group operating around Aboabo No.1, Asawase, Sawaba, and Aboabo post office area.
DCOP Gyening disclosed that the hoodlums, who are always armed to the teeth, seemed to have been emboldened by their juju magical powers, thereby brandishing cutlasses and other weapons with impunity.
