An Irish man is reported to be in a serious condition in hospital in Sydney after an alleged serious assault.

Sydney Morning Herald reports that Jason Cierans - aged 29 and reported to be originally from Cork - was found unconscious outside a pub in the suburb of Bondi Junction.

He is said to be in an induced coma, in a critical but stable condition. He is being treated for serious head injuries.

New South Wales Police say that two men - aged 27 and 30 - were arrested at the scene of the alleged assault.

The 27-year-old man was charged with affray. He was granted conditional bail and will appear in court on Monday.
