The man, identified as Shankar, was detained by the police.
The minor girl (16) was married off to Shankar, a widower at Naput village in the Tamando police station area last week. Shankar married the girl as his first wife died last year and they had two children at home.
While the girl has told the police that she was married to a man more than double her age, Shankar said he was not aware of the law preventing child marriage. He has also refuted allegation of having paid money to the girl's family for the marriage.
The girl has been handed over to CWC for counselling.
