New Delhi, Apr 20 (IANS): Rapists of minor girls reflect a "mental sickness" which needs a "shock treatment" of hanging, Leader of the Opposition in the Lok Sabha Sushma Swaraj said Saturday.

"They reflect a mental sickness which has crept in society...a strong law is not sufficient, they need a shock treatment... They should be hanged to send a strong message to other people," the Bharatiya Janata Party leader told reporters here.

Stating that the stronger anti-rape law passed by the parliament recently was not sufficient to deal with people accused of rape, Sushma Swaraj suggested Home Minister Sushilkumar Shinde should immediately call a meeting of political parties to discuss two changes needed in the law.

"We need two more changes in the anti-rape law...related to minor victims and such horrifying, soul churning instances (brutal sexual assault of a five-year-old girl)," said Swaraj.

A five-year-old girl was abducted April 15 and kept hostage for two days without food and water in a room in which the attacker lived, on the ground floor of the building in east Delhi's Gandhi Nagar, in which the victim's family also stayed.

The accused Manoj Kumar, 25, was arrested from a village in Bihar's Muzaffarpur district early Saturday. The girl has been admitted to the All India Institute of Medical Sciences in the national capital.
