Police have been left red-faced after failing to explain why bail shouldn't have been granted to a man charged with extortion and supporting a terrorist organisation.

Omar Succarieh will remain in custody until a separate Supreme Court bail application over the terror charges occurs in late January.

However, a successful bail verdict in the Magistrates Court on Friday, relating to the extortion charge, was one of two hurdles he needed to clear to achieve his goal of being released ahead of his criminal trial.

Mr Succarieh was arrested in September as part of terror-related raids in Brisbane and charged with sending money and planning to join terrorist group Jabhat al-Nusra.
