The Nollywood actress and ex-Mr Nigeria, who were kidnapped on Monday in Owerri were freed Thursday evening.
The captors reportedly tied their eyes and dropped them off at an unknown location where they were able to call friends to come pick them up.
It is not known yet whether ransom was paid or not.
Nkiru Sylvanus is also the Special Assistant on public matters to Rochas Okorocha, governor of Imo State.
The state government few days ago announced a substantial reward to anyone with useful information about the whereabouts of the abducted actress.
Though details of the incident were still sketchy at press time, it was learnt that the abductors have established contact with her family and have demanded a ransom of N100 million.
