Gaurav Jyoti Neog, reporter of city-based News Live channel, who had filmed the July 9 molestation of a 20-year-old girl in Guwahati, was arrested on Friday on the charge of instigating the attack on her.
The arrest came a day after the Guwahati High Court rejected his anticipatory bail plea.
"Neog has been arrested and will be produced in the court tomorrow," newly appointed Senior Superintendent of Police of Guwahati Ananda Prakash Tiwari said.
Neog was being questioned at Bhangagarh police station.
Team Anna member Akhil Gogoi had accused Neog of orchestrating the molestation of the girl before a bar.
Neog had resigned from the channel earlier this week. Neog's boss and Editor-in-Chief Atanu Bhuyan had also resigned from his post.
The journalist along with his cameraman, had captured the entire incident on camera.
A Special Investigation Team has already decided to send the raw footage of the video for a forensic test.
