Outrage grew after two ministers from India's ruling Hindu nationalist Bharatiya Janata Party (BJP)
attended a rally in support of the accused men.
Details of the injuries inflicted on the minor victim have also horrified many Indians.
The accused include a retired government official, four police officers and a minor.
Prime Minister Narendra Modi only broke his silence on Friday evening with a series of tweets
saying "no culprit will be spared... our daughters will definitely get justice".
