NEW DELHI: Delhi on Monday turned into a fortress a day after violent protests rocked India Gate which was kept out of bounds for people but protests continued in the city which witnessed traffic mess hassling office-goers, students and others.

As the outrage continued over the December 16 gang rape of a 23-year-old student, police said chargesheet will be filed "within a week" in the case even as two assistant commissioners of police were suspended and explanations sought from two DCPs on why the crime could not be prevented.

In a fresh appeal for peace, Prime Minister Manmohan Singh assured that government will look into delay in response in the gan grape case as also all aspects concerning the security of women while asking people to desist from violence.

Cutting short his visit to the US, Delhi Lt governor tejinder Khanna returned to the capital and held discussions with senior police officials and women's groups to chalk out a plan for improving safety of women in the capital.

"We have suspended two ACPs Mohan Singh Dabas (traffic) and Yagram (PCR). I have instructed the police commissioner to seek explanation from DCPs Premnath (traffic) and Satbir Kataria (PCR) and will decide on further action after that," he told reporters.

The condition of the victim has deteriorated and she remained in a critical condition at Safdarjung Hospital, doctors said. "She is still in a critical condition and not out of danger," doctors said.

Security personnel kept Rajpath, the stretch linking India Gate and Raisina Hill leading to Rashtrapati Bhavan, locked down with barricades and heavy deployment of personnel with riot-gear besides disallowing traffic on Rajpath and closing down nine Delhi Metro stations.

It was chaos on roads as police restricted vehicular movement around India Gate leading to huge traffic jams in central Delhi, including near ITO, Mathura Road and roads leading to the VIP areas.

At Jantar Mantar, a number of protesters gathered to demand speedy punishment for the criminals involved in the gang rape but no violence was reported.

Today's protests appeared muted as police did not allow anybody to reach near India Gate or Raisina Hill, which saw pitched battles between security forces and protesters on Sunday leaving around 150 injured from both sides.
