Many people reportedly sustained injuries in an attack on the convoy of Rabiu Kwankwaso, senator representing Kano central, on Thursday.
Abdullahi Haruna, police public relations officer in the state, confirmed the incident which happened at Kofa village in Bebeji local government area of Kano.
A witness said the long motorcade of Kwankwaso was denied passage through Kofa village by suspected thugs said to be working for the All Progressives Congress (APC).
Kwankwaso was heading to the rally alongside Abba Yusuf, the PDP governorship candidate in the state.
Mohammed Wakili, commissioner of police in the state, said he had deployed his men in the area to avoid further breakdown of law and order.
The former APC chieftain has a huge following in Kano, a stronghold of the ruling party.
His Kwankwasiya movement flooded the Sani Abacha stadium in the ancient city with crowd when Atiku Abubakar, presidential candidate of the PDP, campaigned in the state two weeks ago.
