Traces of a drug used to treat leprosy and tuberculosis were found in a blood sample taken in recent months from former Yugoslav President Slobodan Milosevic, a Dutch news report said, citing an unidentified "adviser" to the UN war crimes tribunal.
The report came hours after Milosevic's legal adviser showed journalists a letter the late Serb leader wrote Friday, one day before his body was discovered in prison, alleging that he was being poisoned.
The report was on the text service of the Dutch state broadcaster, NOS. It did not identify its source further.
Doctors found traces of the drug when they were searching for an answer to why Milosevic's medication for high blood pressure was not working, the report said.
