Information on the treatment of members of the Janata Dal Party (JDP) by members of the Congress Party is currently unavailable to the DIRB.
The Xinhua General Overseas News Service reports the arrest of large numbers of JDP members in Tamil Nadu state for anti-government activities (16 Mar. 1993).
An All-India Radio report monitored by the British Broadcasting Corporation states that
[f]ormer Prime Minister of India and Janata Dal leader V.P. Singh was arrested in Gorakhpur on 9th October [1992], along with Janata Dal leaders S.R. Bommai and George Fernandes and several other party workers.... They had been on their way to Ramkola to protest against the police firing on farmers [in October]. Later, Singh was sent to Deoria district jail while Bommai was released (14 Oct. 1992).
While not specifically referring to the treatment of JDP members by the Indian authorities, the following information might be useful. According to a New York Times article, "a group of gunmen" assassinated Mahinder Singh Bhatti, a senior JDP leader, and one of his associates, and wounded his bodyguard in Uttar Pradesh state on 21 September 1992 (22 Sept. 1992, 1). Before his death, state authorities had accused the assassinated leader of "having links to Indian criminal gangs" (Ibid.).
Additional information on the above subject is currently unavailable to the DIRB.
