The crime has renewed public outcry over sexual violence in India.
The 22-year-old Indian woman is in stable condition after being repeatedly raped by up to five suspects in a deserted textile mill while her male colleague was tied up and beaten.
Police from India's elite crime branch are hunting three more suspects named by the first man arrested Friday. Police have released sketches of the men.
Indian politicians and the public have expressed shame and outrage over Thursday night's attack, which drew parallels to the deadly gang rape of a student on a New Delhi bus in December. – Sapa-AP
