The three young men have confessed to the crime, including disrobing and filming the survivor at gunpoint, and could be charged under the National Security Act and the UP Gangsters and Anti-Social Activities (Prevention) Act, Kashi DCP R S Gautam said on Sunday.
Lanka station house officer Shivakant Mishra identified the arrested trio as Kunal Pandey of Sunderpur's Brij Enclave Colony; Anand, alias Abhishek Chauhan, of Jivadhipur Bajardiha; and Saksham Patel of Bajardiha.
Hours after their arrest, social media was flooded with screenshots of Kunal and Saksham's Facebook pages mentioning the positions they hold in BJP's IT cell. BJP's Kashi media in-charge Navratan Rathi said Kunal was the convenor of the cell's city unit while Saksham was its co-convenor.
DCP Gautam said the motorbike and mobile phone used in the crime, besides other electronic evidence, had been seized. The arrested trio's criminal history, if any, is being checked.
Based on the survivor's complaint on November 2, Lanka Police had registered an FIR under sections 354B (use of criminal force to woman with intent to disrobe), 506 (criminal intimidation) of IPC and 66E of the IT Act.
Sections 376 (D) (gangrape) and 509 (outraging a woman's modesty) were added after the student's statement was recorded before a magistrate on November 8.
The survivor said she had stepped out for a walk outside her hostel around 1.30am that night when a male friend from the same institute joined her at the Gandhi Memorial Hostel crossing.
The duo was approaching the Karmanbir Baba temple when the motorbike-borne accused approached them. The survivor was forcibly separated from her friend, dragged behind some bushes and assaulted, she said.
The crime triggered a tumult on campus, with thousands of students joining a sit-in that continued for days.
Later, IIT-BHU students staged a demonstration near the office of the institute's director, protesting the delay in arresting the accused.
The revelation that two of the three alleged culprits were BJP IT cell members sparked a political slugfest in UP on Sunday, with SP's state spokesperson Manoj Rai Dhupchandi accusing the "women-worshipping" saffron party of harbouring rapists.
