The police identified the members of the group as Prabhudev, Nirveni, Shahajan, Shanthi, Girish, Lakshmi, Pappu P, Pappa and Simran—all belonging to the Hakki Pikki tribe. People from the tribe often tour African countries selling herbal oil for head and body massage. The group went to Africa six months ago, according to the police.
