A top security officer who spoke on anonymity made the disclosure to our correspondent in Ile-Ife on Tuesday.
The official said that some inmates had planned to escape during the morning sanitation and while attempting to flee the centre, injured a warder.
He explained that the inmates were about to force their way out when security men repelled them, killing four of them in the process., while others who wanted to escape ran back.
When contacted, Mr Sola Adeotan, Spokesperson, Osun Command of the correctional service, said that it was a rumour as there was no information on the incident.
