Honorary ADC Gen. Shanta Kumar Malla is conducting an internal palace investigation to determine whether security lapses led to a June 1 carnage in the palace killing or injuring 14 members of the royal family and relatives, including King Birendra and Queen Aishwarya. Unauthorized possession of weapons should be banned henceforth and weapons should be returned to a competent authority after use, a study will recommend, the newspaper said.

The five member committee has found Crown Prince Dipendra kept the weapons he used in the shoot-out illegally in the Palace, Naya Sadak said. In a departure from the past practice, security personnel should now be placed on full alert even at family gatherings inside the Narayahiti Royal Palace, the newspaper said. “The incident of the magnitude at the Palace occurred because security personnel had no role in private royal gatherings, ” the newspaper said quoting at unnamed palace official. The report will be presented to King Gyanendra.
