MUMBAI: Shakeel Ahmed Sheikh, a former aide of underworld kingpin Dawood Ibrahim, breathed his last at Jaslok Hospital here on Monday.
Sheikh alias Lambu Shakeel, was suffering from heart disease and had been admitted to the hospital for a few days.
According to reports, Sheikh was one of the key accused in a criminal conspiracy to smuggle explosives into India and conduct blasts at the behest of Dawood Ibrahim.
