A fight broke out between Sam Worthington and photographer Li Shang at 5.30pm on Sunday (EST) outside the Cubbyhole Bar in Greenwich Village, New York, after the photographer reportedly kicked Sam's 'wife' Lara Bingle.
According to Gossip Cop, Sam responded to the kick by reportedly punching the photographer, Li Shang, in the face, telling him, 'You kicked my wife.'
The 'Avatar' actor was taken into custody for assault, and given a desk appearance ticket, meaning he will have to attend court at a future date to face the charges.
At time of publication, the photographer Li Shang was still in police custody, after being booked for endangerment, harassment and assault.
This isn't the first arrest for Sam, who was arrested outside a restaurant in Atlanta in November 2012 for a scuffle with security, after they refused to let him into the restaurant.
Sam has also displayed protective behaviour towards Lara since the part started dating in September last year. At the AACTA Awards in January this year, the actor repeatedly shut down reporters requests on the red carpet for confirmation of the pair's marital status, after a series of cryptic tweets and photos sparked the wedding rumours. The pair have also been spotted wearing what appear to be wedding bands on their ring fingers.
