The five accused, including the driver who is associated with a radio cab service company, have been apprehended and the cab has also been impounded.
"The woman in her complaint to the police said that she had left home around 10.30 pm yesterday to fetch coconut water from a nearby market. She has alleged that while she was walking towards the nearby market, a taxi came from behind and stopped next to her.
"Before she could understand anything, the two men who were sitting on the rear seat in the cab overpowered her and pulled her inside the car. They threatened to kill her if she screamed for help," a police official said.
