Salim Mehajer has been convicted of assault occasioning actual bodily harm after slamming a car door on Channel Seven reporter Laura Banks outside a police station on April 2 last year.

Mehajer had been arrested after allegedly assaulting a taxi driver earlier that morning and was trying to leave the police station when he was followed by a group of journalists including Banks.

As he jumped into the car, he closed the door on Banks, leaving her hand bruised.

In a scathing judgment at Downing Centre Local Court on Friday, magistrate Joanne Keogh said the 31-year-old property developer was "hunted" by a "frenzied media pack" who showed "appalling and predatory behaviour".
