BUCHAREST, Feb 9 (Reuters) - An investigation into the death of Dinamo Bucharest captain Catalin Haldan who collapsed and died during training has been halted because no cause could be found, a medical official said on Friday.
'The causes leading to the Catalin Haldan death have not been clarified and the Romanian Forensic Institute gave us no clear diagnostic over the case,' Ioan Dragan, the National Anti-doping Commission's president told reporters.
'Haldan probably died after a heart attack but I couldn't be sure about it,' Dragan said.
Haldan, skipper of the current Romanian champions, died last October on his way to hospital, shortly after collapsing during a training match near Bucharest.
His death was the latest in a series of unexplained fatalities to hit Romanian soccer in the past few years.
In 1999, Stefan Vrabioru, of Astra Ploiesti, also collapsed and died minutes after his debut in the opening championship match against Rapid Bucharest.
No explanation could be found and a series of investigations excluded doping, disease or blow to the head during play.
Four other soccer players died during matches or training sessions for different reasons in the country during the past year. No coaches, doctors or club organisers were found responsible.
