The Police in the Western Region have arrested four people suspected of being involved in the robbery incident that resulted in the shooting and killing of Lance Corporal Nicholas Duku last Sunday.
The leader of the gang, one Kwaku Mintah, is said to be a Gospel singer.
The dead cop was with the Tarkwa Divisional Command in the region.
According to the police, the suspects admitted to carrying out the operation at the premises of a gold refinery company at Bogoso.
Three of the suspects were reportedly among five persons who were initially arrested by the police in connection with the incident.
The names of the four arrested were given as Frederick Mensah, 32; Bismark Opoku, 34; Charles Kwesi, alias Yaw Laryea, 20 and Mohammed Dauda, 32.
They were arrested in a taxi.
According to the suspects, they were ten in number and were lodging in a hotel at Bogoso where they purportedly planned the whole operation.
They have, however, denied stealing GHS900,000 from the premises of Plant and Plume Refinery Company Ltd as was reported by the police.
The suspects say they rather made away with GHS420,000, which they shared among themselves
