According to the police commissioner, three girls including the victim went to a bar with two boys; they got into a fight. When they left the pub, their fight turned violent.

An editor of a local newspaper, Mukul Kalita, tried to help the girl but was beaten up by the mob. "She held on to me, saying 'Uncle, help me' while the mob heckled her," Mr Kalita told NDTV. The group molested the girl even after she had been rescued by the police and was inside the police jeep in the midst of cops. (Watch)
A reporter from a local news channel, Dipya Bordoloi, said he tried to help the victim when he saw the commotion. "It was almost like a gang-rape," he said, adding that when it was clear that the mob could not be overcome, he began filming the incident for evidence against the attackers. He told NDTV he was disgusted that he couldn't do more to help her. The news editor of the TV channel, Newslive, has said that when it was clear that his reporter could not physically help the victim, he did the next best thing by recording the incident as evidence. This footage is the only reason that arrests are being made, he said.

The minister also objected to the use of the phrase "rape capital" for Guwahati. He said, "I think it's in very poor taste to use phrases as rape capital. Every incident of molesting is condemnable. Such condemnable incidents happen all over the country."
