The girl was reported to have been gangraped first in a paddy field in the village in December last year and again on January 13 at her residence.
"We have detained six of the accused. They all hail from the girl's village and are in the age group of 14-16 years," a senior district police officer told PTI.
He said the detention was made based on an FIR filed by the family members of the girl.
The police officer said the accused have confessed to the crime and have been sent to a juvenile home.
Last year, 101 cases were filed under POCSO and 22 rape cases against children in Meghalaya, according the crime records bureau of the home department.
