Expressing concern over the gang rape of a 19-year-old woman in Noida, the Congress on Tuesday asked the Narendra Modi government to strengthen the criminal justice system and take tangible action to reduce crime against women. "Even as Prime Minister Narendra Modi was inaugurating the new Metro line in Noida, a 19-year-old was gang-raped in a moving car when she was on her way to Noida from Gurgaon," said Congress spokesperson Khushboo Sundar.
