Mr. Oppong-Boanuh was elevated to the second highest office of the Police Service barely three weeks to his statutory retirement at age 60.
Reports say he personally requested an extension of his contract through the Interior Ministry, to enable him assist the IGP, although this is not the normal practice in the service.
The Deputy IGP position, which is part of the Police Service Regulations under Constitutional Instrument (C.I.) 76, has been vacant for many years.
Since the last Deputy IGP, Mohammed Alhassan, was promoted as IGP; the Deputy IGP position remained vacant until the recent appointment of COP Oppong Boanuh.
Some of the Senior Police officers who have expressed dissatisfaction over the role given to COP Oppong Boanuh are of the view that the move blocks the chance of equally competent but younger officers.
