Delhi Police commissioner Neeraj Kumar Monday said he won't resign over sex crimes in the city, adding that his exit won't help remedy the situation.
"If my resigning will prevent (such crimes), then I am prepared to resign a thousand times. But that is not going to address the problem," he told the media.
He said the factors responsible for the rising crimes against women in the city were mental depravity, psychopathy and mental sickness.
"And that won't be sorted out by anyone resigning, least of all the leader of the police force," he said.
Earlier, asked if he would quit, Kumar shot back: "For any misreporting that you do, does your editor resign?
"If you do wrong reporting, does your editor resign? This is my counter question."
The second suspect in the brutal rape of a five-year-old girl in Delhi a week ago was arrested from Bihar late Sunday even as protests continued while police barricaded streets near Parliament to prevent December-like anti-rape protests.
Investigators tracked down the second suspect Pradeep, who was named by first accused Manoj Kumar, from his maternal uncle's home in Barahiya village in Bihar's Lakhisarai district late last night.
A Delhi Police team with the help of Bihar Police Special Task Force arrested Pradeep from his uncle's residence, where he was hiding, Bihar Director General of Police Abhayanand said.
"He will be brought to the national capital today after getting a transit remand from Darbhanga court," Delhi Police commissioner said.
Three Metro stations -- Race Course Road, Central Secretariat and Udyog Bhavan -- close to Parliament, India Gate and Prime Minister Manmohan Singh's residence were also closed anticipating anti-rape protests like the one witnessed in December last after the gangrape of a girl in a moving bus.
The issue figured in Lok Sabha with home minister Sushilkumar Shinde assuring agitating members that an inquiry has been ordered into alleged police lapses.
Protests were witnessed at Parliament Gate, Police Headquarters and Jantar Mantar for the removal of Commissioner Neeraj Kumar.
However, the numbers were not as large as the December protests.
Manoj, who was arrested on Saturday from Muzaffarpur in Bihar, had told police during interrogation that one of his friends was also involved in the crime.
The girl was raped on April 15 in a building in east Delhi's Gandhinagar locality where the victim and accused Manoj lived and she was rescued 40 hours later on April 17.
