The 12-year-old reportedly told police that her father started sleeping with her since she was seven.
Police said Ubong Williams Akpan claimed his wife was looking quite old and no longer attractive to him, hence the recourse to sleeping with his daughter as a substitute.
Detectives arrested him on March 2 when the girl reported the alleged affair to the Divisional Police Officer at Itele Ota divisional headquarters, Monday Unoegbe, a Chief Superintendent of Police (CSP).
She told the police that her father managed to sustain the affair for five years until she could not bear it any longer and had to report him to the police.
Commissioner of Police Edward Ajogun directed that the case be transferred to the family support unit of Ota area command for further investigation and prosecution.
He also directed that the victim be taken to the general hospital for medical examination and treatment.
