Mumbai, Oct 2 (PTI) Former media magnate Indrani Mukerjea, accused of killing her daughter Sheena Bora, today consumed pills in jail after which she was rushed to hospital where doctors said her condition is "serious", leading to speculation that she might have attempted suicide.

"She was brought here at 2 pm. She is unconscious since then. We have done the MRI. We think she has consumed some tablets," T P Lahane, Dean of J J Hospital, told reporters.

"She is unconscious, her condition is serious," he said.

43-year-old Indrani, the prime accused in the sensational murder of 24-year-old Sheena, was rushed from the Arthur Road jail and admitted to the state-run J J Hospital here after she complained of "uneasiness", said DCP Mohan Dahikar.

"We have taken her gastric lavage and sent it to the forensic for investigation. There is respiratory repression.

We are giving oxygen and she is admitted in CCU, said Lahane.

"Whatever toxic has been there, if it has been gone out of the body, then I think, it should be clear to us within the next 24 hours to check the response. It will be take at least 24 hours," he said.

There was speculation that Indrani was under depression and had attempted suicide by consuming some pills.

Indrani was arrested on August 25 for her alleged role in the murder of Sheena, her daughter from a previous marriage, in April 2012. The two other accused in the case are Shyamvar Rai, Indrani's former driver and her ex-husband Sanjeev Khanna.

The high-profile case was initially handled by Mumbai Police under the supervision of the then Police Commissioner Rakesh Maria and later transferred to CBI by Maharashtra government. The central agency last month filed a murder case against the three accused.

On September 7, Indrani was sent to judicial custody.

Her husband, Peter Mukerjea, former Star India CEO, was also questioned several times by police.

Sheena was allegedly abducted by the three accused and killed inside a car after which her body was burnt and dumped into the jungles of adjoining Raigad district, police have said.
