Police detectives are on the trail of suspected armed robbers, who attempted to break into the home of a former Inspector-General of Police, Ibrahim Coomasie.
The police said its preliminary findings did not support allegation of assassination attempt but armed robbery.
A police sergeant was killed in the attack which took place in Katsina on Friday night, and another was injured.
Katsina Police Command says 18 empty shells of expended ammunition were recovered at the scene.
In Ogun , the state Commissioner of Police is taking tough on the menace of crime and criminality in the state particularly on international border routes.
After a meeting with other stakeholders in ensuring a secure state, the police boss says the command is promoting neighborhood watch, in order to trace and fight crime easily.
He further states that actionable intelligence information is evident when police and members of the public work together, which he believes will help in achieving safety and security.
