Protesters breached security and gained access to the government house in Kano, as demonstrations against economic hardship swept through Nigeria on Thursday.
Armed with cudgels and stripped to their singlets in some cases, the irate youths chanted anti-government slogans after erecting bonfires outside the precinct of the government building.
Security operatives unleashed water cannons and teargas canisters on the protesters to keep them at bay and prevent an arson.
Earlier, protesters had looted the newly built Nigeria Communication Commission (NCC) Industrial Park in Kano.
The protest had also turned violent in Yobe, Gombe, Kaduna and Borno. In Yobe, protesters reportedly torched government buses.
In Lagos and Abuja, police used teargas canisters on peaceful protesters.
In the south-east states, most youths did not bother coming out. Streets in Imo, Abia, Ebonyi and Anambra were deserted for hours on end.
