A medical report has confirmed that the Delhi tourist had indeed consumed drugs, and probably an overdose affected her body organs.
Sara Khan is on the road to recovery, three days after she was brought to a private hospital in a critical condition.
She was taken off the ventilator on Thursday and is expected to be shifted out of ICU.
"She is off the ventilator but doctors are closely monitoring her health. She opened her eyes on Thursday. We expect her recovery soon. Her body fluids test has ascertained the presence of narcotics in her body," a senior police officer told The Goan.
Khan, Dr Abhishek Singh, who is a native of Agra and another common friend had arrived in Goa to spend a long weekend. While the unknown friend soon returned to his home state, Khan and Singh stayed back.
On November 19, according to the initial investigation, Khan and Singh decided to attend a party at a Vagator-based club. "They were aware the party is from dusk to dawn. Singh told the police that Khan arranged for entry tickets," the officer revealed, emphasizing that the investigation sleuths will record the 32-year-old's statement once doctors declare her medically fit to join the police probe.
"Every person linked to the case will be questioned. We are waiting for Khan's recovery to record her statement."
The Calangute police on Wednesday registered an offense under sections 21 and 27 of the NDPS Act against the duo while an unknown drug peddler is charged with selling suspected cocaine to both tourists. The First Information Report (FIR) has also added Section 336 (act endangering life or personal safety of others) of the Indian Penal Code against Singh.
The police are investigating the quantity of drugs sold by the supplier to Khan-Singh and if other party attendees had also consumed it.
Suspected drug peddlers, including those involved in past cases, are being rounded up by the local police.
