Police have released an image of two teenagers wanted for questioning over the attack on a Sydney Anglican minister, whose good Samaritan act landed him in hospital with a suspected broken jaw.

Canon Rick Smith, who earlier this year was a candidate to become Sydney's next Anglican archbishop, was attempting to help a teenage pizza delivery driver who was being robbed outside his church residence in Naremburn, on Sydney's lower north shore, when the thugs turned on him and beat him to the ground.

Two of Canon Smith's sons witnessed their father, the Rector of Naremburn/Cammeray, being repeatedly punched and kicked as he lay on the ground during the attack on Saturday night.

Paramedics treated Canon Smith at the scene before taking him to Royal North Shore Hospital, where he was treated for a suspected broken jaw, broken ribs, cuts and bruises, police said.
