Sani was murdered on his way home shortly after a visit to his lover.
Although the police have arrested a suspect, the motive for the attack has not been established.
The deceased, who lived in the Kwari Quarters in Daura, was said to have paid his lover, Amina Suleiman, a visit at her home in the Kurunbai Quarters but was hacked to death by a man who was lurking in the shadows shortly after his companion saw him off.
Northern City News learnt that Suleiman, who witnessed the incident from her home, informed the police that she saw one barber, Sani Salisu (28), committing the crime.
The case was transferred to the Katsina Police Headquarters for further investigation.
The suspect was charged with culpable homicide, which the police said violated Section 221 of the Penal Code.
