A 28-year-old doctor was found dead in his rented accommodation in north-east Delhi’s Dilshad Garden on Wednesday morning. Dr Sharath Prabhu, the deceased, hailed from Coimbatore, Tamil Nadu, and was a first-year student of a postgraduate course in medicine of University College of Medical Sciences under Guru Teg Bahadur Hospital. He was found lying outside the bathroom by around 7am his two flatmates, also doctors,said Deputy Commissioner of Police (Shahdara) Nupur Prasad. She said the cause of death is not known yet but some syringes had been found at the spot. “When they (the flatmates) went near him, they found he was unconscious. They rushed him to GTB Hospital where he was declared dead. A call was also made to the police who reached the house where Prabhu was found dead,” Prasad said. The body has been sent for postmortem. “Some syringes were found and we have handed them over to the doctors. It could be a case of drug overdose or some lethal drug being injected into the body. It will become clearer only after the postmortem report,” Prasad said.Prabhu’s flatmates said he had been showing signs of severe depression for the past one month, mainly due to work-related pressure. According to the doctors, two vials containing insulin and potassium were also found lying near the body, indicating that may have committed suicide. “It cannot be drug overdose, insulin and potassium do not give you a high. Potassium is usually given to patients who have an electrolyte imbalance, but it is given in a very controlled dose because an overdose can be fatal. As for insulin, an excess of it can cause hypoglycemia (low blood sugar). Being a doctor, he was well aware that overdose on both would definitely be fatal for him,” said a doctor on condition of anonymity. Prabhu’s two flatmates, whose names Prasad refused to share, told the police that they had dinner with him on Tuesday night after which he went to his room to sleep around 10.30pm.“We have informed the family. I don’t know as of now, when they will be reaching Delhi. All the procedures, including post mortem, will be done then,” said Dr Sunil Kumar, medical director, Guru Teg Bahadur Hospital and University College of Medical Sciences.Prabhu’s flatmates also hail from Coimbatore and are doctors at GTB Hospital. Prabhu had joined the hospital in May 2017, according to the DCP, Shahdara.
