The death of a second Dalit woman in a few days after an alleged gang rape has shocked and angered India. The 22-year-old was dragged into a vehicle after going to apply for admission at a local school and raped, her mother AFP. The news follows the death of another Dalit woman, 19, on Tuesday after an alleged gang rape by upper-caste men. Dalits are at the bottom of the caste system. Despite laws to protect them, they face widespread discrimination. Both attacks took place in the northern state of Uttar Pradesh. News of the first sparked protests in the streets in the state. Police have registered complaints of rape and murder and arrested two men in connection with the latest case, which took place in Balrampur district. The earlier attack happened some 500km (310 miles) away in Hathras district. The victim was grievously injured and died in a Delhi hospital on Tuesday after fighting for her life for two weeks. Police said on Thursday that according to a forensic report the first victim was not raped. But a Delhi hospital recorded on admission that she was both raped and strangled on 14 September. The woman's family also said she had been raped - her mother telling media that she found her daughter naked, bleeding and seriously injured in a field. The second victim also died on Tuesday but national media picked up the news on Thursday, after a heavy backlash on social media over sexual assault and caste violence in India. Dalits, formerly known as untouchables, have suffered public shaming and attacks for generations at the hands of upper-caste Hindus.
