The Editor Nigeria reports that the police chief disclosed this during a briefing and parade of over 1,000 suspects at the Command headquarters in Ikeja.
Although he didnâ€™t give details on the number of suspects arrested and their connection to the murder, Odumosu said the case was progressing and the police would never compromise on it.
He reminded the public the prime suspect, Chidinma Ojokwu, 21, was still a suspect with her rights guaranteed by the constitution, dismissing insinuations the police were attempting to give her a soft landing.
Odumosu said: â€œWe have established a case of conspiracy in the murder and we have arrested more suspects.â€
Ataga, 50, was killed on June 15 at a shortlet apartment where he was spending weekend with his lover, Ojokwu.
Ojokwu, who earlier confessed to have stabbed the deceased to death before stealing his belongings, later refuted her statement claiming she returned from an errand to find him lying in a pool of his blood.
