A fresh wave of protests spread across India's biggest cities Monday, hours after masked assailants invaded dormitories on an elite university campus in the capital New Delhi and beat up students and faculty.

At the edge of a tree-lined lane in Mumbai, India, Abdul Kareem opens the hood of his taxi and pours water into the radiator. The car is black with a yellow roof, like all Mumbai cabs. But it stands out in a line of cars.

It's antique-looking and kind of boxy, with bulbous headlights. It has a metal luggage rack on its roof that proclaims "Mumbai" in bright orange lettering. On the streets, Kareem says, people point out the taxi to their kids.

On Nov. 27, a veterinarian in the southern Indian city of Hyderabad called her family to say she'd gotten a flat tire on the side of the road. A truck driver was helping her, and she'd be home soon, she told her sister.

A few days later, police found her charred remains in a wooded area. Authorities believe four men deflated her tire, posed as good Samaritans to trick her, then gang-raped and murdered her. Police said they have DNA evidence connecting them to the crime.
