Four males attended the Victoria Street milk bar and jumped the counter shortly after 9pm.

Staff have fought back and managed to restrain one of males, a 17-year-old boy, until police arrived.

The three other males fled the scene.

Two staff members were injured – a 54-year-old man was taken to hospital with non-life threatening facial injuries and a 31-year-old man was treated at the scene for minor facial injuries.
