Dawood Ibrahim, India’s most wanted criminal, is suffering from severe gangrene in his legs that has left him crippled. The doctors at Liaquat National Hospital, Karachi and the Combined Military Hospital, Karachi, where the D-Company's boss is being treated, said his legs may have to be soon amputated.

The mastermind behind the deadly 1993 serial bomb blasts that shook Mumbai is now immobile. He is receiving treatment at his residence in the upscale Clifton neighbourhood of Karachi.

Doctors treating Dawood told CNN-News18 that at this stage of his disease he is unlikely to be cured fully.

Loss of effective local blood supply due to high blood pressure and blood sugar has caused the disease that is accelerated when lack of oxygen due to limited or no blood supply leads to cell death. The gangrene that the international gangster suffers from is said to be life threatening.

Dawood is unlikely to be moved outside of Karachi, where he gets full support and the protection of Pakistan’s intelligence agency ISI, for treatment.

The news of his deteriorating health may hamper India’s efforts to bring the gangster to justice, especially at a time when Islamabad has been denying of his presence in Pakistan for the last two decades.

The sixty-year-old is wanted in India for financing and supporting the 1993 serial blasts in Mumbai that killed 257 and left around 717 injured. One of his accomplices, Yakub Memon, was hanged to death last year.
