"Every case against women are being registered on priority basis," Chand told IANS.
According to data of the National Crime Records Bureau (NCRB), Delhi registered the highest 568 cases of rape in the country followed by 218 in Mumbai in 2011.
Delhi, which earned the infamous tag of 'rape capital', saw street campaigns, especially by the young, in 2012 after a 23-year-old physiotherapy intern was gang raped by six people, including a minor, and died later of grievous injuries.
Following the shocking incident, Delhi Police took several steps to ensure safety of women.
Another senior police officer told IANS that data have shown that in 90 percent of cases, people known to the victims were involved, while a small percentage were committed by strangers.
"In most of the rape and molestation cases, the accused were known to the victim and this makes prevention of such crimes comparatively more difficult," the officer, who did not want to be identified, told IANS.
