SOFIA, Bulgaria (AP) — Bulgaria's highest court says it will look into a petition by the chief prosecutor to revoke the parole by a lower court to an Australian man convicted of fatally stabbing a Bulgarian student during a 2007 brawl.

The Supreme Court of Cassation announced Thursday it will hold a hearing Oct. 23 to review a lower court's ruling to grant parole to Jock Palfreeman. The Australian man had served 11 years of his 20-year prison sentence when a three-judge Court of Appeals panel unexpectedly ordered him freed last Thursday.

The 32-year-old left prison but was transferred to an immigration detention facility to await a new passport from the nearest Australian Embassy, in Athens.

The release of the Australian has sparked angry reactions among Bulgarians, who accused the judiciary of double standards and a leniency toward foreigners.
