The case was registered under the Indian Penal Code, Information and Technology Act, Scheduled Caste and Scheduled Tribes and Protection of Aboriginal Tribes, official sources said here today.

Andaman and Nicobar Police have formed a special team led by a Deputy Superintendent of Police which will seek help of cyber cells of central agencies in cracking the computer from where it has been hosted.

The case has been registered under section 292 of Indian Penal Code (showing obscene material), section 67 of IT act (Publishing of information which is obscene in electronic form), section 3 (2) of Schedule Caste and Scheduled Tribes (forces a member of a Scheduled Caste or a Scheduled Tribe to drink or eat any inedible or obnoxious substance).

The case has also been registered under section 7 (entering buffer zone for commercial activities) and section 8 (promoting tourism activities through any advertisement about Jarawa tribes) of Protection of Aboriginal Tribes.

The issue had sparked controversy when London-based newspaper 'Observer' reported the alleged incident and also uploaded a video.

The Centre has sought a report from the Union Territory administration.

In its preliminary report, the administration had said it would initiate prosecution against the videographer involved in the coverage for a British newspaper for "inciting" the tribals to dance in front of tourists.

The video footage was condemned as "obnoxious and disgusting" by Union Tribal Affairs Minister V Kishore Chandra Deo. According to reports, there are just 403 surviving members of the Jarawa tribe who live in reserve forests on south Andaman.

The Home Ministry had directed the local administration to find out when the video was photographed, how the primitive tribals living in seclusion came in contact with outsiders and to find out the people responsible for their exploitation.
