Abdulmumin Jibrin, a member of the house of representatives, has been arrested by the Kano state police command over the attack on the convoy of Rabiu Kwankwaso, senator representing Kano central.
Jibrin, a member of the All Progressives Congress (APC) was among the suspects arrested over the attack which occurred on Thursday.
He is a known loyalist of President Muhammadu Buhari and convener of the Parliamentary Support Group which has repeatedly pledged alliance to the president.
The motorcade of Kwankwaso who is of the Peoples Democratic Party (PDP) was reportedly denied passage through Kofa village by suspected thugs said to be working for the APC.
The incident resulted in a clash between the PDP and APC supporters.
