Police in the Indian capital Delhi are investigating the alleged gang rape of a Danish woman who lost her way near her city centre hotel, the BBC News reported. The 51-year-old tourist was attacked by a group of men in the Paharganj area on Tuesday evening. Police say she was robbed and raped at knife point. A German woman has also been raped in south India, Der Spiegel reports. 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. But violence and discrimination against women remain deeply entrenched in India's staunchly patriarchal society. The Danish woman told police that she approached the group of men after losing her way back to her hotel near New Delhi Railway Station.
