Two police officers in India have been sacked for refusing to help search for two missing girls who were later found gang-raped and hanged, officials say.
They were also charged with criminal conspiracy, police said, adding that three people had been arrested so far.
The government has pledged to set up a fast-track court to prosecute the crime, which took place earlier this week in the state of Uttar Pradesh.
Alleged police inaction sparked outrage in the teenagers’ village.
The father of one victim told the BBC he was ridiculed by police when he sought help in finding his missing daughter.
He said that when policemen found out he was from a lower caste, they “refused to look for my girl”.
Authorities said on Friday that they were still looking for two other suspects.
Meanwhile, reports are emerging that two more gang rapes of minors occurred in the state this week.
‘You are safe’
The chief minister of Uttar Pradesh reacted angrily when asked about the rising number of rape cases at a news briefing.
“You are safe, why are you bothered?” Akhilesh Yadav told a journalist.
“No other state has the kind of police control room we have here. If there is any incident, we will take action.”
Senior police official Atul Saxena earlier announced there would be a “thorough investigation” into the allegations of caste discrimination by police.
Divisions between India’s castes run deep, and violence is often used by upper castes to instil fear in lower castes, correspondents say.
Although both the victim and the accused in the latest case belonged to a group known as “Other Backward Classes”, the victims were lower in that hierarchy.
The girls, two cousins aged 14 and 16, went missing in Badaun district on Tuesday night. They had apparently gone out to relieve themselves as they had no toilet at home.
Their bodies were discovered the following day. A post-mortem examination confirmed multiple sexual assaults and death due to hanging.
Campaigners have highlighted the lack of sanitation in rural areas as being a risk to women’s security as well as their health, as they are often attacked when having to go out to use the toilet, particularly at night.
Scrutiny of sexual violence in India has grown since the 2012 gang rape and murder of a student on a Delhi bus.
The government tightened laws on sexual violence last year after widespread protests following the attack.
Fast-track courts were brought to the fore to deal with rape and the death penalty was also brought in for the most extreme cases.
Some women’s groups argue that the low conviction rate for rape should be challenged with more effective policing rather than stiffer sentences.
