The anti-graft agency, EFCC, has denied arresting Rochas Okorocha, the immediate past governor of Imo State.
There had been media reports that Mr Okorocha was arrested alongside his wife, Nkechi, and two others by the EFCC on Thursday.
”I am sorry the reports are fake news,” he said.
Asked if an investigation was being carried out regarding the former governor, Mr Magu responded, “definitely”.
Mr Okorocha enjoyed immunity from arrest and prosecution for the eight years he was governor. He left office on Wednesday and was succeeded by Emeka Ihedioha.
