Mikhail, an important witness in the case, said in the mail that his grandfather was bed-ridden for the past one year and he was looking after both his grandparents for the last three years without any financial and psychological support from Indrani.
His grandparents had legally adopted him as their son and he has already commenced the post-death rituals, he said.
"Indrani has been accused of murdering my elder sister Sheena Bora and ruining my family. Therefore it is my utmost plea that I don't want Indrani to come to Guwahati and visit me as this will create chaos and unnecessary disturbance in my life due to media and other persons, and will hamper post-death rituals of my grandfather," Mikhail said.

Meanwhile, according to a statement of Indrani's former driver Shyam Rai, the accused-turned-approver in the case, she reneged on her promise to help him after Sheena's murder.
Rai's statement, recorded by police last year (before CBI took over the case), was given to the defence lawyers yesterday.
"During the period (after the murder) I asked for money but she did not help me," he told the police.
Indrani had earlier promised to take care of his children's school and his family's medical expenses, he claimed, adding that she had also assured she would hire him as a permanent staff.
Last June, judge H S Mahajan had made Rai an approver in the case and granted him pardon.
According to CBI, Indrani, her former husband Sanjeev Khanna and Shyam Rai killed Sheena, Indrani's daughter from an earlier relationship, in a car here in April 2012.
