evidence: "See this. This is the most important document for me. This is the document that comprises Savarkar’s letter to [the> British in which he has stated ‘I beg to remain, sir, your most obedient servant, VD Savarkar," the Congress leader alleged on Thursday at a press conference in Maharashtra’s Aloka, as he brandished a letter, which he claimed is written by Savarkar. [...] Savarkar, who was arrested for his alleged links to the assassination of AMT Jackson, a British district magistrate of Nashik, was lodged in the Cellular Jail, a colonial prison in the Andaman Islands, infamously called "kaala paani". His elder brother Ganesh was also in the same prison. The two spent 10 years in jail between 1911 and 1920 and during this time Savarkar reportedly wrote to the British at least seven times.
