The man was killed on Thursday evening.
The police have recovered the motorcycle that was allegedly used to trail a professor at Ahmadu Bello University Zaria, Hyacinth Mbibu, before he was killed on Thursday night.
The spokesperson of the Nigeria Police Force in Kaduna, Aminu Lawan, said this on Friday.
Mr. Lawan also said the force is on the hot trail of the assailants and is confident they will be arrested soon.
The police spokesperson said he is not sure if the person shot was a professor.
“All I can tell you is that someone who works with the ABU Teaching Hospital was shot somewhere in Zaria, not Shika, by some unknown gunmen,” he said over the telephone.
The deceased, initially thought to be from Cameroon, has been described as an indigene of Takum in Taraba State.
He was shot by gunmen on a motorcycle shortly after he closed from work on Thursday.
A nurse from Ahmadu Bello University Teaching Hospital, who was riding with him, was also shot and is receiving treatment at the hospital.
Sources quote the nurse to have said that one of the assailants was familiar and looked like a patient that was receiving treatment at the hospital.
When prodded, the police spokesperson said, “investigations have commenced and we are making progress; that is all I can tell you for now.”
