Article Today, New Delhi: In a dramatic revelation, Delhi Police have unearthed a secret heroin trafficking network allegedly run by 52-year-old Kusum Rani. Hidden within the narrow lanes of Sultanpuri, her home functioned as the nerve centre of an elaborate drug operation. What appeared to be four separate houses from the outside was in fact one interconnected structure. The internal walls had been demolished and reconstructed to resemble a fortress, with iron grills, automatic gates, and controlled entry points.
Mastermind Behind a Covert Empire
Following the arrest of her son Amit in March, Kusum went underground. Investigators say her intelligence and use of spy-like methods stunned even seasoned officers. She had designed intricate drug delivery systems. Her associates would drop heroin packets from windows using ropes or push them through narrow slots in walls—avoiding all personal contact.

Surveillance and Child Lookouts
Kusum had installed 17 CCTV cameras around the premises. These monitored every movement in and around the house, even at night. To strengthen vigilance, she employed local children to act as informants. They would track who entered and exited the neighbourhood. Any suspicious movement would trigger a rapid response to hide or relocate drugs.
Arrest and Seizure
Months of surveillance led police to act swiftly in March. They intercepted a supplier near the Sultanpuri house and launched a raid before anyone inside could react. Kusum’s son Amit, aged 26, was arrested from the scene. Officers recovered 550 small packets of heroin, Tramadol tablets, Rs.14 lakh in cash, and a Scorpio SUV. Subsequently, authorities confiscated eight properties—seven in Sultanpuri and one in Rohini Sector 24. Police confirmed these were acquired using profits from drug trafficking.
Suspicious Transactions Under Scrutiny
Investigators are now probing the family’s financial history. Kusum’s two daughters reportedly deposited nearly ₹2 crore across multiple bank accounts over the past 18 months. These transactions were often broken into smaller sums between Rs.2,000 and Rs.5,000 to avoid detection. Notably, Rs.70 lakh was deposited during the first half of this year alone.
History of Drug Cases
Kusum Rani is no stranger to the law. She has 12 drug-related cases registered across various police stations and crime branches. Authorities believe her network may extend beyond Delhi. With further interrogation and digital forensics underway, police hope to unravel the full scale of this underground empire.
