Police in India have arrested six men after they allegedly gang-raped a woman on a bus, just weeks after a similar attack shocked the nation.

The latest assault is said to have taken place in the northern state of Punjab. The police are searching for a seventh suspected attacker.

Last month, a 23-year-old student died of her injuries after being raped in the capital Delhi.

Five men have been charged with her murder and are facing trial.

If convicted, they face the death penalty.

A sixth suspect, who is thought to be 17, will be tried separately in a youth court if it is confirmed he is a minor.

The Delhi attack prompted mass protests which prompted the government to set up special fast-track courts to exclusively deal with rape cases and also consider strengthening sexual assault laws, the BBC's Sanjoy Majumder reports.

Night attack

Police officials say that the latest victim was a 29-year-old woman.

She is believed to have been travelling on a bus back to her village on Friday night.

The driver and conductor allegedly refused to stop at her village, instead taking her to a desolate location not far from the city of Amritsar.

The two men are then believed to have been joined by five others and taken turns raping the woman throughout the night.

The victim was then dropped off near her village, where she was able to tell her relatives about the attack.

The extent of the woman's injuries were not immediately known.
