Indian officials are promising a broad campaign to protect women on buses as they arrested a fifth person in connection with the rape and brutal beating of a woman on a bus in New Delhi.

Home Secretary R.K. Singh said Friday that bus drivers would be required to display their identification prominently, buses would be forced to remove tinting from their windows and plainclothes police would be placed on buses to protect female passengers.

Last weekend's gang-rape of the 23-year-old student has sparked days of protests across the country from women demanding authorities take tougher action to protect them.

Delhi Police Commissioner Neeraj Kumar said police arrested a fifth suspected attacker Thursday night and were hunting for the last assailant.
