Former media executive Indrani Mukerjea, arrested for the alleged killing of her daughter Sheena Bora, was discharged today from the J J Hospital and was taken back to the Byculla prison, a senior official said.
Her health condition is better, the hospital's dean Dr S D Nanandkar said.
She subsequently underwent a series of medical tests.
Her urine samples were sent for analysis at a forensic laboratory here and after receiving its report, the hospital authorities said she had an overdose of anti-depressants that were not prescribed to her.
"The reports of her urine sample showed a significant increase in the level of benzodiazepine, a class of anti-depressants," a doctor from the hospital had said, quoting from reports of the Forensic Science Laboratory at Kalina.
The IG (prisons) will submit his report to the department after completing the inquiry.
Bora (25) was allegedly killed and her body disposed of in a forest area in the neighbouring Raigad district in April 2012, according to the police.
