Onome was arrested in the Badagry area of the state alongside four accomplices, who allegedly aided the sale of the girl.
The state Police Public Relations Officer, PPRO, SP Dolapo Badmos, who confirmed the arrests to newsmen, said Onome, who worked as a commercial sex worker in the Mobil area of Badagry, allegedly sold Zainab to another sex worker, simply identified as Endurance.
According to the PPRO, Onome was arrested on Saturday by the Badagry Police Division after a tip-off.
Badmos said Endurance gave Zainab’s mother N50,000 before taking the girl away, adding that the mother said she used the money to buy a few things for herself.
“The fleeing buyer, who is of no fixed address, fled with the girl to a yet-to-be-ascertained location to resell her. But the police are on her trail.
“As at press time, Zainab is yet to be found but the mother has confessed to be a commercial sex worker, and also to the crime.
“Effort is ongoing to track the fleeing suspected buyer and the child,” the police image maker added.
