Salihu Yakasai, a former special adviser on media to Kano State Governor Abdullahi Ganduje, has departed Nigeria.
Mr Yakasai announced his departure in a tweet on Wednesday evening, saying “Japa….. Goodbye Naija! Alhamdulilah!”
His destination via a Qatar Airways flight could not be immediately confirmed.
Yakasai was sacked in February for criticising President Muhammadu Buhari over the security challenges bedevilling the country.
While reacting to the abduction of 317 students in Zamfara, he said the APC at all levels had failed in its promise to secure the populace.
He was also arrested by the Department of State Services hours after criticising the president.
Yakasai, who is the son of elder statesman Tanko Yakasai, was suspended by Ganduje last year for criticising Buhari. He was, however, reinstated soon after.
