Manipur Police has got in touch with the two women, who were paraded naked in May and then sexually assaulted, and was in the process of recording their statement, officials said here on Friday.

They said keeping in mind the situation arising out of ethnic clashes that broke out in the state on May 4, a team of women officials and personnel from Manipur police was formed to probe the case.

The officials said the team had met the family members as well as the two women and the process of recording their statements has begun.

The process of identifying eyewitnesses and recording their statement has also begun, they added.

According to top government sources in New Delhi, the cases pertaining to the sexual assault was likely to be handed over to the CBI. Reacting to the arrest of people in the viral video case, spokesperson of the Indigenous Tribal Leaders Forum (ITLF) Ginza Vualzong termed it "too little, too late".

"I would have appreciated it if the culprits were arrested before the video went viral. The FIR was registered on May 18. There are many more such cases. Having said that I would also like to clarify that arresting people would not solve the larger issues of the state which has been witnessing ethnic clashes.

"I request the Centre to take the Manipur issue seriously and take steps to end the violence and come up with a solution," he said.

Police have arrested as many as seven people including a juvenile in connection with the case so far.

Tension had mounted in the hills of Manipur after a May 4 video surfaced on June 19 showing two tribal women being paraded naked by some men from the other side in Kangpokpi district.

Police had registered a case of abduction, gangrape and murder at Nongpok Sekmai police station in Thoubal district against unknown armed persons.

The video which drew widespread condemnation shows men constantly molesting the two helpless women, who cry and plead with their captors to spare them.

Prime Minister Narendra Modi and Chief Justice of India D Y Chandrachud had expressed deep anguish and called the incident "shameful" and "unacceptable".

Manipur has been witnessing ethnic clashes since May 3 between the majority the Meiteis, concentrated in Imphal valley, and the Kukis, occupying the hills. Over 150 people have been killed in the violence so far.

Manipur Chief Minister N Biren Singh had said he will ensure strict action is taken against all the perpetrators, including considering the possibility of capital punishment.

"My heart goes out to the two women who were subjected to a deeply disrespectful and inhuman act, as shown in the distressing video that surfaced yesterday," Singh had tweeted.

"A thorough investigation is currently underway and we will ensure strict action is taken against all the perpetrators, including considering the possibility of capital punishment. Let it be known, there is absolutely no place for such heinous acts in our society," he said.

Meiteis account for about 53 per cent of Manipur's population and live mostly in the Imphal Valley, while tribals, which include Nagas and Kukis, constitute 40 per cent and reside mostly in the hill districts.
