Delhi Police is investigating three types of comments in the case of Gurmehar Kaur, a 20-year-old Delhi University student and army martyr's daughter, who was allegedly abused by netizens. Police are scanning comments, trolls and abuse comments.

"Police are also preparing a list of the people who have issued threats," police sources said.

In social media, basic comments and trolls are natural that's why police are  not giving much attention like abuse, but they are also not taking them out of context.

"Cases cannot be filed against the basic comments," police sources added.

Police sources further claimed that they have identified several handlers who have abused the DU girl, some of the accounts have been de-activated by the users but it will no affect the investigation.

After Gurmehar moved the Delhi Commission for Women (DCW) with her complaint against those allegedly threatening her with rape and violence, Delhi Police registered an FIR against unknown persons under Sections 354A (sexual harassment and punishment for sexual harassment), 506 (punishment for criminal intimidation) of IPC and Section 67 of the IT Act.

Sources claimed that police are identifying the areas from where the accounts were active during the time when abuses were hurled at the girl.

Meanwhile, Delhi Police has been in touch with her through telephone calls and emails.

However, Gurmehar still has not given the investigators the URL of her abusers that will help identify the user accounts responsible for the incident. The police said they are in touch through the email, but are yet to receive the links.

“From the first day itself, the cyber cell has been investigating the case on the basis of the screen shots, and we can’t book some users just on the basis of screen shots. How can the police filter the real users from non-pertinent threats?", said a source.

Gurmehar, daughter of martyred Captain Mandeep Singh, started the social media campaign, "I am not afraid of ABVP" following recent violence in and around Ramjas College on DU's North Campus. It went viral and received massive support from students across universities.

Police also said they have written to various social networking sites and it will take about 15-20 days for them to answer their queries.
