Man charged over Central Coast 'one-punch' attack

A man who allegedly knocked another man unconscious in a one-punch attack outside a pub on the NSW central coast has been arrested and charged.

A 24-year-old Wyong man is in a critical condition in Royal North Shore Hospital after being punched in the back of the head during an argument in the hotel's car park at Erina at around 12.45am yesterday.

The punch caused him to fall and strike his head on the pavement.

Police said that at around 2.30pm yesterday a 22-year-old Long Jetty man was arrested at a home at Long Jetty and charged with causing grievous bodily harm to a person with intent.

Brett McMonagle faced Gosford Local Court where he was granted bail with strict conditions today.

He will reappear in court on January 5.

In January this year, “one-punch laws” were introduced to tackle alcohol-fuelled violence in Sydney.
