Patna, Sep 7 - The widow of slain Patna businessman Satyendra Singh has demanded that a polygraph test be conducted outside Bihar on Janata Dal-United (JD-U) leader and former MP Vijay Krishna, the prime accused in the abduction and murder of her husband.

Voicing her anger over the delay in conducting a polygraph test on Vijay Krishna, Laxmi Singh said here Monday that the test should be conducted outside the state 'to expose the real truth'.

Krishna, in his late 50s, was arrested from Faridabad in Haryana last month. The JD-U leader and his son Chanakya are accused in the murder of Singh.

'We fail to understand why a polygraph test on Vijay Krishna was delayed on health grounds despite the fact that he was healthy.
