South Sydney officials are pleading for the support of their members as they continue their search for the person behind the socket-throwing incident at Sunday's NRL match against Manly.

The hunt is still on for a patron sitting within the Rabbitohs' members area who allegedly threw a small metal socket at Sea Eagles centre Steve Matai as he made his way from the field after being sent to the sin bin just before halftime.

The socket - the size of a five-cent coin - narrowly missed a Sea Eagles trainer who was accompanying Matai up the tunnel.

Closed circuit television footage of the incident has failed to identify the offender, with Souths continuing their investigations with NSW Police, officials from ANZ Stadium and Manly.

A statement issued on the South Sydney website called for members or patrons at the game to come forward with any information regarding the incident.

Rabbitohs chief executive Shane Richardson has vowed to issue a life ban on the perpetrator.
