NEW DELHI: Home Minister Rajnath Singh launched a mobile-phone based application Thursday for the safety of women in the capital.

The app - Himmat - is an initiative of Delhi Police. It will allow smartphone users to call the police control room and also trigger a 30-second audio and video recording at the press of the phone's power button.

Police said Himmat will help users contact police in the quickest possible time in an emergency.

The user will be asked to feed five emergency contact numbers of friends or relatives into the app's data base. When an SOS call is made, a message will be automatically sent to these five numbers.

"In this way, not only police, but the user's relatives and friends too will be able to come to her rescue," an officer said.
