POLICE are hunting a group of thugs who set upon a couple at a city karaoke bar.

The victims were drinking at the Elizabeth Street venue when a group of men attacked them earlier this month.

The 25-year-old male victim was punched and kicked until he was unconscious on the floor.

His 23-year-old girlfriend was also set upon as she rushed to his aid, the group throwing her to the floor by the hair as she attempted to defend herself.
