Fayose advised the former governors to surrender themselves without revealing the reason.
He made the call in the wake of speculations that Okorocha and his wife, Nkechi, had been arrested by the anti-graft agency.
“Just reading that Okorocha was arrested by EFCC. True or not, we knew this day will come,” he tweeted.
“However, I welcome him to the EFCC Alumni & enjoin the commission not to look away from Amosun too.
“While I encourage them to surrender themselves as I did, I welcome Mr Okorocha to the club.”
