A photojournalist has been gang-raped by five men while out on assignment with a male colleague in south Mumbai. The woman, 22, is now in intensive care with reports suggesting she suffered multiple injuries, both internal and external.

Her condition is described as critical, but stable. The man the victim was with in an area known as Lower Parel was tied up and assaulted.

The victims' statements have been recorded and sketches of suspects have been released by the police. Two of the attackers reportedly called each other by name - Rupesh and Saijid.

Police said they have arrested five people over the gang-rape.

The latest attack comes after the gang-rape and death of a 23-year-old physiotherapy student on a bus in Delhi last December. That incident caused nationwide protests and demands for stringent laws against rape.

Under pressure, the government instituted fast-track courts for crimes against women and six men were subsequently charged with rape and murder. The case is in its final stages at the Saket fast-track court in Delhi and a verdict is expected soon.

Suspected ringleader Ram Singh killed himself at the Tihar jail earlier this year. A juvenile is being tried at a separate court as he was under 18-years-old when he allegedly committed the crime.

The other four await their fate when the court delivers its verdict.
