Rivers Police Commissioner, however, dismissed Fayose's claims, saying it cannot be true.
He said security operatives, with an armoured personnel career, blocked the old Presidential lodge in Rivers state Government House where he lodged, preventing him from going out.
In a statement titled "I was under ‘house arrest’ in PH - Fayose", and issued by his media aide, Mr Lere Olayinka, the Governor said several appeals to the security team at the gate to allow him attend the convention were shunned.
The statement said: "Fayose Governor Ayo Fayose of Ekiti State has lamented that he was not at the national convention of the Peoples Democratic Party (PDP) because he was placed under ‘house arrest’ at the Old Presidential Lodge, Rivers State Government House where he lodged.
"All entreaties to allow Fayose to step out to attend the convention were rebuffed by the security personnel on ground.”
The State Commissioner of Police, Mr Francis Odesanya, however, dismissed Fayose's claims, saying it cannot be true.
He said other Governors got out of their lodge to attend the PDP meeting, wondering how Fayose's case was different.
