A lawyer for Ratko Mladic on Thursday said that the former leader of Bosnian Serb military was treated in a Belgrade hospital for cancer while he was running away from genocide charges two years ago.

Milos Saljic, a lawyer based in Belgrade, said he has medical records that will prove Mladic was treated in 2009. The lawyer said Mladic has suffered from lymphoma, a cancer of the lymph nodes, and that he went through chemotherapy and surgery in a Belgrade hospital.

The records were only acquired after Mladic was arrested and copies of them were given to the Serbian war crimes prosecutor, said Saljic. However, he refused to disclose the names of the doctors who had handled Mladic and the clinics where he had went.

According to Saljic, Mladic had two heart attacks and three strokes, the Belgrade daily Press reported Thursday. The publication released a document which showed Mladic’s name, his birth year, and other personal information. The document also revealed that Mladic was diagnosed with “non-Hodgkin Lymphoma.”

The report said that Mladic, 69-years-old, underwent surgery because of stomach ulcer complications, which was thought to be caused by the disease.

However, managers of the major hospitals that treat patients with cancer in Belgrade rejected the likelihood that Mladic was admitted and treated there three years ago, the daily Press said.

Mladic has been the most wanted man in Europe. He was arrested last Thursday in northeast Serbia and was deported on Tuesday to The Netherlands. He will be asked to plead before the UN Court to 11 counts of war crimes, crimes against humanity and genocide on Friday.
