The Police Command in Kaduna State has revealed that six people died during an attack on the Emir of Potiskum, Alhaji Umaru Bubaram, on Kaduna-Zaria highway on Tuesday night.
The command spokesman Yakubu Sabo told the News Agency of Nigeria (NAN) that the incident occurred at about 11:00 pm.
NAN gathered several people might have been abducted by the attackers as empty vehicles were left at the scene when government officials visited on Wednesday.
He said four of those killed were aides of the emir, while two were commuters.
Sabo said the Commissioner of Police Umar Muri had visited the emir at the hospital.
