Nearly four weeks after a family of four was found dead in their south Mumbai home, investigators remain baffled by one of the strangest poisoning cases in recent Indian memory — a tragedy that began with a late-night slice of watermelon and ended with four bodies, an entire fruit market in panic, and a forensic mystery that has yet to be solved.
Abdullah Dokadia, his wife Nasreen, and their daughters Ayesha and Zainab were discovered dead at their first floor apartment in the Pydhonie area of Mumbai on April 25, 2026. What initially appeared to be a sudden, devastating illness has since been confirmed as poisoning by zinc phosphide, a highly toxic compound commonly sold as rat poison. But how the chemical ended up on the family’s watermelon — and whether it was placed there by accident, by their own hand, or by someone else — remains entirely unknown.
The case, which Indian media quickly branded the “watermelon deaths,” has dominated headlines for weeks, triggered a crash in watermelon prices across Mumbai fruit markets, and prompted widespread public warnings about the safety of the country’s most beloved summer fruit.
A Late-Night Snack Turns Deadly
On the evening of April 25, the Dokadia family hosted relatives for a dinner of biryani at their home. The guests reportedly left around 10:30 p.m. Sometime between 1:00 a.m. and 1:30 a.m., the four family members ate watermelon — the last thing they would ever consume.
Within hours, all four were violently ill, suffering from vomiting and diarrhea. Neighbors in the old building rushed to help, including Dr. Zaid Qureshi, who lived on the fourth floor. He found the youngest daughter, Zainab, struggling to breathe and immediately began CPR.
“I noticed that the youngest of the four individuals was experiencing difficulty breathing. I administered CPR. However, as her condition did not improve, she was taken to a nearby hospital. She passed away,” Qureshi told BBC Marathi.
The remaining three were transferred to JJ Hospital in Mumbai for intensive treatment. Zainab died at 10:15 a.m. on April 26. Nasreen and Ayesha followed shortly after. Abdullah, the father, succumbed at 10:30 p.m. that same day. Doctors performed stomach wash procedures and provided intensive medical care, but the toxin had already done its work.
The Forensic Breakthrough
For eleven days, investigators struggled to identify what had killed the Dokadias. The Forensic Science Laboratory in Mumbai conducted 54 tests on samples seized from the home, including half-eaten watermelon rinds, spices, kitchen articles, and food items. The State Food and Drug Administration also examined the items for adulteration.
On May 7, the FSL submitted its findings to Mumbai Police. Zinc phosphide had been detected in the viscera of all four deceased — in their liver, kidney, spleen, stomach contents, bile and abdominal fat — and crucially, in the watermelon samples as well. The chemical was not found in any other food item tested.
Deputy Commissioner of Police Pravin Mundhe confirmed that police had registered a case of accidental death, while the JJ Marg police station continues to record statements from relatives and neighbors. Post-mortem reports are still awaited.
Police sources told reporters they are still collecting evidence and looking at all angles for motives, and have not ruled out homicide, accidental death or suicide.
How Zinc Phosphide Kills in Minutes
Medical experts say zinc phosphide is an inorganic compound containing phosphorus and zinc, widely sold as rat poison and easily available across India. When ingested, it reacts with stomach acid to produce phosphine gas — an extremely toxic substance that spreads through the body, crosses into cells, and shuts down their ability to produce energy. The cells then die, and oxygen levels in the body plummet.
Symptoms typically begin within 30 minutes to an hour and include vomiting, dizziness, breathing difficulty and convulsions. In severe cases, the poison causes liver and kidney failure, delirium, and coma. According to forensic experts cited in coverage of the case, treatment is only viable within a roughly one-hour window. After that, even aggressive medical intervention is unlikely to succeed.
Dr. Hemalata Arora, an internal medicine specialist, explained that stomach wash procedures are effective only within that narrow timeframe. Dr. Rukmani Krishnamurthy, a former FSL director, noted that zinc phosphide is usually sold in powder form, raising the possibility that the substance was applied directly to the cut watermelon. Forensic official Dr. Bhushan Rokade and Dr. Sanjay Surase have also weighed in, with experts suggesting the youngest child likely died first because her smaller body could not withstand the toxin.
Unanswered Questions and a City on Edge
Investigators say the building has a known rodent problem, but there was no indication that rat poison was kept inside the Dokadia home. That has left police considering every possibility — from accidental contamination to deliberate tampering. Reports have suggested two fruit sellers were arrested in connection with applying rat poison on fruits, though the link to the Dokadia case has not been formally established.
For now, the city of Mumbai is left with a chilling unanswered question: how did a household staple, eaten in the middle of the night, become the instrument of an entire family’s death? Until investigators can piece together the final hours before that fatal slice, the watermelon deaths will remain one of India’s most haunting forensic puzzles.
