Police crackdown amid outrage over gang rape Russian President Vladimir Putin is due visit India Monday New Delhi's government district is under a lockdown Protesters demonstrate after the gang rape of a woman on a bus Police say the woman was badly beaten and left for dead New Delhi (CNN) -- Police locked down New Delhi's key government district ahead of Monday's visit by Russian President Vladimir Putin, after two days of pitched street battles following the gang rape of a woman on a bus. Putin is scheduled to meet with Indian prime minister Manmohan Singh Monday afternoon and later with the Indian president. Authorities erected security barriers throughout the city's Raisina Hills area -- home to the presidential mansion, the parliament building and federal ministerial blocks. Only those authorized to work in the district were allowed to pass. Furious weekend demonstrations rocked Raisina Hills as public outrage surged after a 23-year-old woman was sexually assaulted and beaten to near death on a bus on December 16 by a group of six suspects, now under arrest, police say. Singh again expressed solidarity with the rape victim in a televised address on Monday. He also reiterated an earlier appeal for calm and a pledge of safety for women and children. On Sunday, incensed protesters defied a police ban on demonstrations, clashing repeatedly with police. As officers sprayed water cannons, some dispersed, while others huddled tightly in a circle to brave high-pressure streams in the cold December weather. Authorities also fired tear gas to try to break up crowds. Police spokesman Rajan Bhagat said "hooligans who had joined the protesters" hurled stones, injuring 78 officers on Sunday. At least 65 protesters were also injured, he said. Many police vans and a dozen public buses were damaged during the demonstrations, he said. Buy Sunday night, the scene was cleared of all protesters. Earlier in the day, Singh called for calm after clashes escalated. "We will make all possible efforts to ensure security and safety to all women in this country," the Indian leader said. I appeal to all concerned citizens to maintain peace and calm. In his statement, Singh acknowledged that the anger is "genuine and justified." But on Sunday, she underwent another surgery to wash out infection in her abdomin, her doctors said. The protests were among many anti-rape demonstrations staged across the country over the past week. The journalist, identified by the information and broadcasting ministry as Dhij Mani, was covering a protest against a separate molestation case in the provincial capital of Imphal. Protests have rocked Manipur over the alleged molestation of a local actress by a suspected militant on December 18, during a public performance, authorities say. Protesters torched a vehicle, forcing police to open fire, officer Manik Longjam said Sunday. The journalist died in the gunfire, Longjam said. Police say the molester is still at large. Reported rape cases have increased more than tenfold over the past 40 years -- from 2,487 in 1971 to 24,206 in 2011, according to official figures. India's home minister Sushilkumar Shinde told reporters Saturday that the government would work toward increasing punishment in "rarest of the rare" rape cases.
