The arrest of top cop Davinder Singh while ferrying militants in his car, a day after he received foreign envoys at the Srinagar international airport, has brought back memories of a 2004 letter by Parliament attack convict Mohammad Afzal Guru to his lawyer in which Singh was named. Then an officer with J&K Police’s Special Task Force (STF), Singh was accused of forcing Afzal to take one “Mohammed”—one of the militants who would be killed during the Parliament attack on December 13, 2001—to Delhi, “rent a flat for his stay and purchase a car for him”.
