Thousands protest during anti-rape rallies in India; journalist killed NEW: A journalist is killed in Manipur covering a protest against sexual assault For a second day, protesters are blasted with water cannons in New Delhi Demonstrators slip under police vans to deflate tires Police say a woman was gang-raped and badly beaten on a bus New Delhi (CNN) -- Thousands of protesters defied a ban on demonstrations in New Delhi on Sunday, venting their anger over a gang rape incident. For a second day, demonstrators were blasted with water cannons in the Indian capital. While some dispersed, others huddled tightly in a circle to brave high-pressure streams in the cold December weather. "We want justice!" the protesters shouted in chorus. In addition to banners and cardboard placards, many demonstrators carried Indian flags as they scuffled with police. Authorities fired tear gas to try to break up crowds. Earlier Sunday, authorities put up security barriers and banned protests in central New Delhi to prevent a repeat of clashes that broke out a day earlier. India rape protest Saturday's demonstration was prompted by public outrage over what police said was the gang-rape and beating of a 23-year-old woman on a moving bus in the capital on December 16. Authorities haven't released the name of the rape victim, but protesters are calling her "Damini," which means "lightning" in Hindi. "Damini" is also a 1993 Bollywood film whose lead female character fights for a housemaid, a victim of a sexual assault. We support you Damini. We'll keep fighting for you," a middle-aged woman at the historic India Gate said Sunday. "Damini wants justice," read a placard at the protest. Police bundled scores of young protesters into buses in the Raisina Hill area, home of the India Gate, the presidential palace, the parliament building and ministerial offices. Demonstrators slipped under police vans to deflate tires and prevent them from driving off. Officers dragged them out. The rape victim's injuries were so severe she spent days in intensive care in a city hospital, battling for her life. Police said Saturday that she had recovered enough to give a statement to a magistrate from her hospital bed the night before. Police spokesman Rajan Bhagat said up to 35 protesters and nearly 40 police personnel were injured Saturday. The protest was among a number of anti-rape demonstrations held across the country in the past week. A video journalist was killed by police gunfire Sunday during a violent protest in India's remote northeastern state of Manipur, authorities said. The journalist, Th. Nanao, was covering a protest against a separate molestation case in the provincial capital of Imphal, state police said. Protests have rocked Manipur over the alleged molestation of a local actress by a suspected militant on December 18, during a public performance. Protesters had torched a vehicle, forcing police to open fire, officer Manik Longjam said Sunday. Nanao died in the gunfire, Longjam said. Police said the molester was still at large. Official data show that rape cases have jumped almost 875% over the past 40 years -- from 2,487 in 1971 to 24,206 in 2011. Six suspects, including the bus driver and a minor, have now been arrested in connection with the rape of "Damini." As fury about the assault gathered pace, some Indian lawmakers called for treating rape as a capital crime. "We'll work collectively to see we make a law which is deterrent and preventive," said New Delhi's chief minister, Sheila Dikshit. Shinde said the government was pushing for a speedy trial for the attack. Government also respects the right of legitimate protest," Shinde said. Following the brutal assault, the country's human rights body sent notices to city police and federal authorities, demanding an explanation. Home Secretary R. K. Singh announced the suspension of five police officers in the wake of the rape.
