A 23-year-old photojournalist has been gang-raped by five men in the Indian city of Mumbai, police say.
The woman, who was on assignment on Thursday evening in the Lower Parel area when she was attacked, is in hospital with multiple injuries.
She was accompanied by a male friend who was beaten by her attackers. Police say 16 people have been detained.
In a similar incident last December, a 23-year-old student was gang-raped on a bus in the capital, Delhi.
In that case, the victim and her male friend were brutally assaulted and the woman later died in hospital from her injuries.
The incident sparked nationwide protests and forced the authorities to introduce tougher laws for crimes against women.
The victim of Thursday's attack worked with a Mumbai-based English magazine and had gone to the Shakti Mills - a former textile mill that now lies abandoned and in ruins - for a shoot, police said.
She has been admitted to Jaslok hospital in Mumbai and police say they are questioning the detained men.
"This is a very serious matter. We have taken note of it. The accused will be arrested soon," Maharashtra Home Minister RR Patil told reporters late Thursday night after visiting the woman in the hospital.
The incident has led to outrage in India.
