NEW DELHI (AP) — Police said today they have arrested six suspects in another gang rape of a bus passenger in India, four weeks after a brutal attack on a student on a moving bus in the capital outraged Indians and led to calls for tougher rape laws.

Police officer Raj Jeet Singh said a 29-year-old woman was the only passenger on a bus as she was travelling to her village in northern Punjab state on Friday night. The driver refused to stop at her village despite her repeated pleas and drove her to a desolate location, he said.

There, the driver and the conductor took her to a building where they were joined by five friends and took turns raping her throughout the night, Singh said.

The driver dropped the woman off at her village early Saturday, he said.

Singh said police arrested six suspects on Saturday and were searching for another.

Gurmej Singh, deputy superintendent of police, said all six admitted involvement in the rape. He said the victim was recovering at home.

Also on Saturday, police arrested a 32-year-old man for allegedly raping and killing a 9-year-old girl two weeks ago in Ahmednagar district in western India, the Press Trust of India news agency reported. Her decomposed body was found Friday.

Police officer Sunita Thakare said the suspect committed the crime seven months after his release from prison after serving nine years for raping and murdering a girl in 2003, PTI reported.

The deadly rape of a 23-year-old student on a New Delhi bus in December led to the woman's death and set off an impassioned debate about what India needs to do to prevent such tragedies. Protesters and politicians have called for tougher rape laws, police reforms and a transformation in the way the country treats women.
