The presidential candidate of the Peoples Democratic Party, Atiku Abubakar, said on Sunday that security agents at the international airport in Abuja harassed him shortly after arriving in the country from a foreign trip.
Mr Abubakar has been away in Dubai, the United Arab Emirates capital, since mid-October when he proceeded on a vacation days after emerging victorious at the national convention of the PDP, Nigeria's main opposition platform.
"I arrived to Abuja this morning to a search by agents of the state, aimed at intimidating me and my staff," Mr Abubakar said on his Twitter handle shortly before 4:00 p.m. Sunday. "I am committed to building a Nigeria where no citizen is intimidated by agents of state who are paid to protect them."
Mr Abubakar did not immediately say which security agencies were responsible for the search he found objectionable, but immigration officials, State Security Service and the police are usually found at the airport for such searches.
He also did not say whether or not the security personnel raised any issues during or after conducting their search.
