Taboga filed charges, claiming he was forced to pay Kuljic nearly 30,000 euros ($40,200) and was threatened by the former Austria international after refusing to prevent Groedig from winning matches.
Kuljic was arrested in a parking lot in Anif near Salzburg on Nov. 12 while waiting for Taboga, expecting the player to hand over 3,000 euros ($4,020). Taboga had warned the police the evening before.
Prosecutors said Kuljic has denied the alleged attempt at match-fixing, adding that Taboga owed him money from the time they both played at Kapfenberg in the first half of 2012. Prosecutors were investigating the cause and extent of Taboga's debt.
The 36-year-old Kuljic retired last year after tearing ligaments. He scored three goals in 20 games for the national team from 2005-2007.
