According to a report surfaced earlier it was claimed that Dawood has been diagnosed with gangrene in his legs which is not likely to be cured.
Gangrene disease is caused by the loss of effective local blood supply due to high BP blood sugar.
His fitness has been confirmed by both Shakeel and senior intelligence officials, reported the Times of India.
"This kind of rumour is being spread to damage the D-Company's business," Shakeel was quoted as saying. Shakeel also claimed that the Indian agencies are ill informed about the don who is said to be the mastermind of 1993 Mumbai serial blasts that left more than 200 people dead.
India has intensified its efforts to nab Dawood,who is believed to currently living in Karachi, fled from India in 1986.
Pakistan has denied time and again the fugitive's presence on its soil.
The report also claimed that Dawood is currently getting treated at the Liaquat National Hospital and the Combined Military Hospital, Karachi under the protection of Pakistan's Inter-Services Intelligence (ISI). Reports further suggest that ISI is unlikely to move him out of the country.
Dawood along with Tiger Memon and Yakub Memon had orchestrated 1993 Mumbai serial blasts. Last year, Yakub Memon was hanged to death after court found him guilty in the case. Both Dawood and Tiger are still rooming free.
