The Inspector-General of Police, Mohammed Adamu, has directed investigators from the force headquarters, Abuja, to take over investigations into the murder of Vera Omozuwa.
A statement issued on Tuesday by the force spokesperson, Frank Mba, said Mr Adamu's directive follows a preliminary report from a team of investigators and forensic experts deployed from Abuja to Edo to assist in the investigations.
The police spokesperson said the inspector general has called on members of the public to provide useful information that could help in the investigations of sexual assaults and domestic violence across the country.
The federal government, through the Minister of Information, Lai Mohammed, Tuesday, directed the police to arrest and bring to justice Ms Omozuwa's killers.
Mr Mohammed said bringing the killers to justice would send "strong notice" about the government's "total aversion to gender-based violence in whatever form".
