A man has been charged after stabbing a Tony Abbott volunteer with a corkscrew on Sydney’s Northern Beaches.

At about 8pm on Friday night, several volunteers were putting up signage outside a school on Lewis Street at Balgowlah Heights.

A man turned up and started yelling abuse at the volunteers before allegedly threatening an 18-year-old man.

Police have been told he thrust a corkscrew at the stomach of a 31-year-old man, causing a minor injury.

He then started ripping down the banners, before fleeing the scene.

Paramedics treated the volunteer at the scene while police began investigating.

Within a few hours, officers arrested a 62-year-old man at a nearby home.

He has been charged with two counts of common assault and been granted conditional bail ahead of his court appearance next month.
