As many as nine students were killed over the issue of revamping and restructuring the Meghalaya Board of School Education. Mr Sangma is contesting the March three Assembly elections from Tura constituency. Yesterday, West Garo Hills District Electoral Officer E P Kharbhih served a showcause notice on NCP's chief ministerial candidate after the family members of the victims of the firing lodged a formal complaint against Mr Sangma's alleged attempt to gain electoral mileage out of the firing incidents. The relatives have also demanded that the video clippings in the CD must be deleted. The CD titled ''Chakat A' chik Me 'a Me'chik'', which means ''Arise Garo men and women'', was supposed to be part of the NCP's election campaign. It shows Mr Sangma, the Lok Sabha MP from Tura, speaking on the need to bring about a change for the betterment of Garo Hills as well as Meghalaya.
The CD also has video-clippings of Mr Sangma meeting top leaders of the world, including former US President Bill Clinton, Queen Elizabeth of England and the king of Saudia Arabia.
