About 12.45am a man was walking through the railway station when he approached a stranger and allegedly slapped him across the cheek.

A short time later the same man approached another male, also unknown to him, police say, and allegedly hit the man across the face with a swinging arm.

The man was treated by paramedics at the scene for swelling and a cut to the eye.

Police spoke to the two men who were allegedly hit and shortly afterwards arrested a 26-year-old man close by in Bijou Lane.

The man was charged with assault occasioning actual bodily harm and common assault.

He was refused bail and is expected to appear in Central Local Court on Friday.

In June a man allegedly punched a baby girl in the face at Central Station.

The 16-month-old was in her pram with her parents outside a cafe on Eddy Avenue when a 28-year-old man approached and punched the baby in the face before fleeing, police alleged.

The baby suffered a cut to her face and was treated at the scene by paramedics.

The man was charged with assault occasioning actual bodily harm.
