Hyderabad Arsenic Case: Why UK Court Cleared Mupparapu’s Extradition
A UK court has ruled that British-based pharmacist Ajith Kumar Mupparapu can be extradited to India to face trial over alleged murder and conspiracy plots targeting his estranged wife's family.
A United Kingdom court has ruled that a British-based pharmacist can be extradited to India to face trial over a series of alleged murder and conspiracy plots targeting his estranged wife’s family. According to Hyderabadmail, Ajith Kumar Mupparapu, 46, faces charges connected to four separate incidents that unfolded in the Indian city of Hyderabad following divorce proceedings initiated by his former wife, oncologist Dr Sirisha Muttavarapu. Westminster Magistrates’ Court determined that the material submitted by Indian authorities disclosed a valid case to answer, clearing a major legal hurdle in the cross-border criminal investigation.
The legal proceedings in London saw the Crown Prosecution Service (CPS) present arguments on behalf of Indian authorities as reported by Mathrubhumi English, while Mupparapu’s defence team aggressively contested the move. Legal representatives for the Indian-origin British citizen argued that the evidence presented lacked sufficiency and raised severe concerns that he could face torture, prison overcrowding, and trial delays if surrendered to authorities in India noted Siasat. However, District Judge John Zani ultimately concluded that formal assurances provided by Indian officials regarding custody conditions adequately addressed those risks.

The extradition hearing itself took place in April, with the judgment subsequently handed down in writing later. Mupparapu was arrested in Britain in January 2025 and has remained in custody during the extradition proceedings.
The core of the prosecution case centres on a complex series of plots allegedly orchestrated after Dr Sirisha Muttavarapu sought a divorce. Prosecutors detailed four distinct criminal episodes allegedly occurring across the year 2023. The primary allegations involve an arsenic poisoning conspiracy directed at Sirisha and her relatives. Investigators maintain that Mupparapu’s sister acquired arsenic, and a delivery worker was paid to leave tainted salt and chilli powder outside the family's apartment in Miyapur. The family had gathered in the area for a wedding in June 2023, specifically for Sirisha’s brother Purnender’s wedding. Multiple relatives subsequently developed symptoms after consuming the items, with medical tests confirming the presence of arsenic. The suspected poisoning came to light after Sirisha’s sister-in-law underwent further medical examination, and investigators also examined arsenic found in spices recovered from the apartment.
| Incident Phase | Alleged Method | Targeted Family Member | Reported Outcome / Context |
|---|---|---|---|
| Primary Incident | Arsenic-laced salt and chili powder | Wife Dr Sirisha Muttavarapu and family | Multiple relatives developed symptoms; mother-in-law died July 5, 2023 |
| Second Incident | Succinylcholine injections | Father-in-law Hanumantha Rao Muttavarapu | Co-conspirators allegedly involved in administration plot |
| Third Incident | Hired contract killers | Father-in-law Hanumantha Rao Muttavarapu | Attempted recruitment in India to murder the victim |
| Fourth Incident | Staged road accident | Father-in-law Hanumantha Rao Muttavarapu | Co-conspirators hired to orchestrate a fatal staged crash |
The tragic turning point of the alleged poisoning conspiracy occurred when Sirisha's mother, Uma Maheshwari Muttavarapu, died in Hyderabad. Telangana authorities launched a sprawling homicide investigation into the death, which later expanded to encompass additional plots targeting the family patriarch, Hanumantha Rao Muttavarapu. According to court disclosures, these supplementary plots included plans involving succinylcholine injections, the attempted hiring of contract killers, and a coordinated scheme to assassinate the father-in-law via a staged road accident designed to look like a routine collision.
It is vital to note that the Westminster Magistrates’ Court ruling does not establish guilt or innocence. UK extradition hearings are strictly designed to evaluate whether legal requirements are satisfied, whether dual criminality exists, and whether human rights safeguards are met. The court's acceptance of government-level assurances cleared the path for the transfer, though the actual determination of criminal responsibility remains entirely with the judicial system in India.
The extradition process now moves into its next administrative phase, which includes final review and sign-off by the Home Secretary. Defence lawyers retain the right to seek formal permission to challenge the ruling through an appeal, meaning physical surrender to Indian authorities is not immediate. If extradition is ordered and there is no successful legal challenge preventing surrender, he could then be returned to India to face the proceedings.
