Three of the accused were already facing criminal charges.
According to police, a 22-year-old medical student and her male friend were returning from a party on Wednesday night when a group of men allegedly surrounded their car on a highway, about 18 km from Mangalore city. They were confined in a secluded guest house till early hours of Thursday morning.
The two friends were allegedly forced in to sexual act, which was filmed and then were blackmailed to keep this under wraps.
The gang had demanded Rs 25 lakh from the students for not posting the video on the internet.
They said that if they fail to provide the money, the video will be uploaded on internet and will be sent to their parents and the principal of their college.
Scared by the threat, the friends agreed to pay Rs. 3 lakh.
Based on leads available, the police nabbed the accused on Saturday and have seized weapons, ATM cards, cell phones and car from them.
