Vanrammawii had disappeared from her grandparents' house on Sunday as she played with the alleged kidnapper, who was reportedly a guest in a nearby house.
"The teenage girl was found near a quarry with the six-year-old girl. Both were safe. We have taken the kidnapper into custody but have so far not been able to interrogate her," said a policeman from Kolasib.
He added, "An angry mob from Kawnpui came in vehicles and we had to keep them away from the accused for the whole afternoon."
