Germany will ask Croatia to extradite an alleged communist-era secret police agent when the former Yugoslav republic becomes a member of the European Union.

A spokeswoman for the German Federal Prosecutors Office said Thursday that Josip Perkovic is sought in connection with the 1983 killing of Stjepan Djurekovic, a Croatian dissident in what was then West Germany.

Frauke Koehler told The Associated Press that the extradition request would be made "in accordance with the law" but declined to provide details.

Croatia joins the EU on July 1, which will make it easier for Germany to seek the extradition of a Croatian citizen.

A German court previously convicted a former Yugoslav agent to life in prison in 2008 for his part in the murder of Djurekovic in Wolfratshausen, near Munich.
