Four men were arrested this week in connection with the alleged brutal gang rape of two minority women who were stripped and paraded through a street in northeast India earlier this year, sparking major public outrage when footage of the attack subsequently went viral.

The four individuals were taken into custody on Thursday in Nongpok Sekmai in the Thoubal district of the Manipur state, the Manipur Police stated.

“The State Police is making all…efforts to arrest the other culprits at the earliest. Raids are continuing,” the official update read.

News of the arrests came one day after footage of the vicious May 4 attack went public, the BBC explained.

The women in the video, aged 21 and 42, were part of a group running from the village as it was burned by the mob of 800 to 1,000 people, according to The Guardian.

While fleeing, they were surrounded by another mob, which forced them to strip and walk down a crowded road while being molested before being gang raped in a field.

Two Kuki men from their group were also allegedly beaten to death by the same mob, The Guardian said.

Manipur, which is sandwiched between Bangladesh and Myanmar, is divided by ethnic clashes that reached a fever pitch in the spring, when the minority Kuki people demanded tribal recognition from the Meiteis, who represent the state majority, the BBC noted.

Thus far, at least 130 people have been killed with an additional 60,000 displaced.

The attack on the Kuki women may have been in retaliation for false reports that a Meitei women had been raped by a Kuki men, The Print reported.

The emergence of the disturbing footage inspired renewed criticism of the local police, who did not take action over the attack for more than 70 days, The Guardian reported.

One of the women in the video even alleged that the police gave the victims to the mob, the outlet said.

The police are also accused of ignoring the ongoing ethnic violence, including beheadings and targeted violence against women.

Backlash from the gang rape footage forced Prime Minister Narendra to make his first public statement on the Manipur conflict.

The attack on the Kuki women, Modi said Thursday, “shamed India” while “no guilty will be spared,” per the BBC.

“I assure the nation, the law will take its course with all its might. What happened with the daughters of Manipur can never be forgiven,” he continued.

India’s Chief Justice DY Chandrachud added that the Supreme Court was “deeply disturbed over the video.”

On Thursday, the Indian government also ordered Twitter and other social media sites to stop sharing the viral video, a source familiar with the investigation told CNN.
