The interim bail granted in a graft case to Director ,\u00a0B K Bansal, whose wife and daughter had allegedly committed suicide, was today extended till August 5 by a Delhi court. Special CBI Judge Gurdeep Singh extended the relief granted to the officer and put up on August 5 his plea seeking extension of his interim bail till August 23. During the hearing, Bansal told the court that he was cooperating in the ongoing investigation and whenever there is a need, he will join the probe. Bansal's application, however, was opposed by CBI which claimed that during the relief period granted to Bansal, he was called to join the ongoing investigation a number of times, but he did not turn up. He, however, denied the allegation. The court, thereafter, fixed August 5 for hearing arguments on the plea. On July 22, Bansal had alleged before the court that CBI had compelled his wife and daughter to take the extreme step. Bansal, an additional secretary-rank officer in the Ministry of Corporate Affairs, was arrested on July 16 for allegedly accepting bribe from a prominent pharmaceutical company. His wife Satyabala (58) and daughter Neha (28) allegedly hung themselves from ceiling fans in separate rooms at their residence in Nilkanth Apartments in east Delhi's Madhu Vihar on July 19. Both the women have left separate suicide notes, saying CBI raid had caused "great humiliation" and they did not want to live after that. They, however, held nobody responsible for their death.
