On Saturday evening, he again suffered from severe pain in the chest following which the prison medical staff checked him and rushed him to the J J Hospital, he said.
"Mukerjea was admitted to the hospital on Saturday evening for chest pain. The patient's condition is stable and he is undergoing treatment," J J Hospital's medical superintendent Dr Sanjay Surase said.
The CBI told a special court here earlier this month that Mukerjea is the "silent killer" of Sheena Bora, the daughter of his wife and former media executive Indrani Mukerjea from a previous relationship.
Indrani Mukerjea, her former husband Sanjeev Khanna, Rai and Peter Mukerjea were subsequently arrested in the case. Rai later became an approver and was pardoned.
The CBI has claimed a financial dispute led to the killing of Sheena Bora.
