NEW DELHI (AP) — Authorities have sealed off a high-security zone in the Indian capital for a second day to put an end to a week of demonstrations against the brutal gang-rape of a woman on a moving bus.

With police blocking roads in central New Delhi, dozens of demonstrators on Tuesday gathered at a venue about a kilometer (less than a mile) from the parliament building to press the government to ensure the security of women.

A police officer injured in Sunday's clashes with protesters died in hospital and police filed a murder case against some protesters, said police spokesman Rajan Bhagat.

The demonstrations have continued despite promises by the government that it will consider protesters' demands that all six suspects who have been arrested following last Sunday's attack face the death penalty.
