The 13-year-old girl was forced to marry the man after her 18-year-old sister run away on the day of the marriage.
The young girl reportedly spent the night with her husband in the same room after the marriage ceremony, and did not go to school on Monday.
The 25-year-old man told Joy News he will leave the young girl after a week to enable the 13-year-old further her education.
But DOVVSU said the child’s marriage is an offence under the children’s act.
DSP Eunice Ida Odonkor, Deputy Greater Accra coordinator of DOVVSU, told Joy News now that the attention of the Unit has been brought to the issue, they will make sure the case goes to court if parties involved are found culpable.
