An investigating judge on duty at the Salzburg federal court on Saturday morning set extradition custody for former Croatian Prime Minister Ivo Sanader, Austrian media said citing prosecution spokeswoman Barbara Feichtinger.
The extradition custody will last at least 14 days, she said.
Sanader had to respond to a question about his identity and allegedly had an attorney present at the hearing.
Sanader is in good health, Austrian news agency APA said citing a representative of the Salzburg court, Dietmar Knebel, adding that the first physical check-up was done and that Sanader would be examined by a physician on Monday.
"Every arrestee who is turned over to us must undergo a physical examination," said Knebel.
According to APA, Sanader is sharing a cell with a man suspected of theft.
Sanader was arrested near Salzburg on an international warrant issued by Croatia. Croatia's anti-corruption agency USKOK suspects him of conspiracy to commit crime and of abuse of office in the case of the marketing agency Fimi Media and in the illegal sale of electricity by the state-owned power company HEP to the petrochemical company Dioki.
