Mikhail has claimed that Indrani tried to kill him the very day Sheena Bora was allegedly murdered.
According to reports, Mikhail is believed to have told the police officials that on the day Sheena was murdered Indrani called him to her flat where she spiked his drink.
However, Mikhail left Indrani's flat after he felt giddy and now fears for his life.
Meanwhile, Mumbai Police Commissioner Rakesh Maria addressed reporters on Friday night and said that they had recovered skeletal remains of Sheena and would send it for DNA testing on Saturday.
Maria also said that they had recovered Sheena's passport from Dehradhun.
