Following the defeat of Rajapaksa at the presidential election in January 2015, the new government announced that it would re-investigate several unsolved high-profile assassinations, including that of Pararajasingham, which occurred during Rajapaksa's nine-year reign. Two TMVP paramilitaries, Pradeep Master (Edwin Silva Krishnanandaraja) and Gajan Maamaa (Rangasami Kanaganayagam), were arrested by the Criminal Investigation Department (CID) on 8 October 2015 in connection with Pararajasingham's assassination. Pillayan (S. Chandrakanthan), leader of the TMVP, was also arrested by the CID, on 11 October 2015, in connection with the assassination.
