People of about 24 villages and members from various social organisations and political parties gathered at Gumma demanding justice for the victim and expediting the CBI probe.
The protestors carrying placards raised slogans and demanded "exemplary" punishment for the perpetrators of the crime.
The local residents alleged that the police investigations were not going in the right direction and expressed apprehensions that the evidence might be destroyed before CBI handles the probe.
Six people were on Thursday arrested in connection with the crime.
