Wearing pink saris and wielding bamboo sticks, this is the Gulabi Gang - the feminist face of India.
Set up in 2006, the gang came into being as an independent force of justice with the aim of "punishing" oppressive and violent fathers, husbands and brothers.
It was formed by Sampat Pal Devi, in the Banda District of Uttar Pradesh in Northern India, and now with a membership numbering in the tens of thousands, the group finds itself performing "interventions" on behalf of men too.

Its website pledges to challenge "all human rights abuses inflicted on the weak."
Following the death of a 23-year-old gang rape victim last week, women's rights have shot to the top of India's social agenda, and the Gulabi Gang has demanded justice.
Devi told The Times of India: "The rapists should not be hanged as it would not serve any purpose, instead they should be chemically castrated. The line, 'I am a rapist', should also be permanently etched on their foreheads.
"This is the lesson which should be taught to the Delhi rapists and many others will never dare to approach a girl with bad intention."
Five of the accused have been charged with rape and murder, while a sixth suspect who claims to be under 18, is expected to be tried in a juvenile court separately, The Associated Press reports. Under Indian law juveniles cannot be prosecuted for murder.
A police report seen by the Hindustan Times states the youngest suspect "extracted her intestine with his bare hands and suggested she be thrown off the moving vehicle devoid of her clothes."
The Indian media reports the police are pushing for the death penalty, yet the Gulabi gang is opposed to capital punishment.
Devi believes the death penalty "worsens the scenario instead of mitigating the problem" and believes illiteracy is the reason for the growing incidents of rape.
She explained: "A significant chunk of the women in Bundelkhand is illiterate, and hence lacks the confidence to be self-reliant. These traits of the women provide advantage to men who try to exploit them."
They have also stormed a police station and attacked a policeman after they took in an untouchable man and refused to register a case.
Devi adds: "There are so many struggles that women here have to go through, it never seems to stop.
"We don't like using violence, but sometimes that's the only way people listen."
During the rape which came to galvanise the nation, the victim was attacked by six men on a bus. A metal rod was inserted in her body as the bus drove around for 40 minutes. The sustained attack resulted in the removal of almost all of her intestines.
The victim and a male friend, who was also attacked, were thrown from the bus while it was still moving. Police in Delhi said the bus then tried to mow them down.
Sampat Pal Devi founded the Gulabi Gang in 2006
The unidentified woman died after suffering multiple organ failure and a heart attack.
In the days following her death, British Indians including professionals from the medical, business and legal sector have written a letter to the UK Indian ambassador Dr Bhagwati and the Indian Prime Minister, Manmohan Singh, calling for urgent action to ensure the protection of women in India against sexual violence.
Amid a renewed campaign to tackle the widespread and often unreported incidences of violence against women, the government has been forced into action. More police night patrols have been set up, buses with tinted windows or curtains have been banned and drivers of public transport are now subject to more checks, reported the BBC.
A telephone helpline has also been set up.
However social activists insist not enough is being done to tackle India's rape culture.
New Delhi has emerged as the 'rape capital' of India, with 25% of cases across the whole of India occurring in the capital, according to an Al Jazeera report.
A woman is raped in Delhi every 14 hours, according to figures quoted by the BBC.
Despite this, official figures show that there was only one conviction for rape in the whole of 2012. On 26 December, a 17-year old girl who had been gang-raped in Delhi was found dead, a note by her body blaming her attackers.
It had taken over two weeks for her case to even be registered, amid allegations that officers had pressured her to withdraw her case and marry her attacker.
On a positive note however, since the attack took place on December 16, there has been a surge in female interest in self-defence classes in India, and shopkeepers have reported a spike in the sales of pepper spray and rape alarms, AFP reports.
