The warning is contained in a statement signed by Dr Samuel Madaki, the INEC Resident Commissioner in the state, and made available to the News Agency of Nigeria (NAN) on Sunday in Bauchi.
The commissioner also warned political parties against backing such campaigns, reminding them that the law prohibiting all campaign activities at this time was still in force.
He said the commission was unhappy over the activities of some politicians aspiring for public offices in the state who have since commenced campaigns.
“The commission has noticed the posting of campaign posters of some aspiring politicians throughout the state, which was wrong and against the law.
“Some programmes on radio and television stations aired and aimed at promoting certain individuals politically must stop or defaulters would be brought to book.
“These activities are in contradiction of the Electoral Law 2010 and whoever flouts it, will be dealt with accordingly,” he said in the statement.
Madaki added that any politician, political party or their representatives found guilty of flouting the law, would be liable to a fine of N500, 000. (NAN)
