The incident has caused a scene in Yola, Adamawa state.
Faro said his action was due to “extreme poverty” in Nigeria.
He said, “I think it’s time for Buhari to give way for someone like Atiku Abubakar to lead us out of the present hardship.
“I will remain here for 12 hours to show my discontent, and someone not less than Atiku must come here to assure me that this government must be sacked in the forthcoming election.”
Meanwhile, a large crowd gathered at the bottom of the tall billboard hanger, chanting “Sai Baba Buhari!”.
Faro’s actions are coming weeks after a 28-year-old man, Nura Ilyasu climbed a telecoms mast to protest against President Buhari’s second term bid in Abuja.
