Billy Nean, 18, appeared via video link in Tamworth Local Court yesterday after he was charged for his alleged part in the mass fight.

The 18-year-old is the latest and the fourth member of his family to be charged over the February 25 incident which saw 200 people spill onto the streets.

Nean has pleaded not guilty to affray, behaving in an offensive manner and common assault.

Steven Nean, 52, along with Steven James Blacklock, 28, will also fight the charges against them after a brief of evidence was served.

They will join fellow co-accused, Steven Leslie Nean, 29, and Wayne Nean, 27, who remain bail refused over the incident, at a hearing in May.

The showdown in court will hear detailed evidence of the large scale affray which involved up to 200 people as they swarmed Cossa St.

More than a dozen officers were called in to try and defuse the situation, with extra officers brought in from across the Western Region to back up local crews.

Police maintain when they tried to break up the street fight they were allegedly pelted with objects.

No police were injured in the affray but they will allege in court that a number of offenders were armed with bottles and rocks.

Four people had to be treated by ambulance paramedics and were hospitalised with minor injuries before they were released.

The court will hear from dozens of witnesses about what happened during the height of the incident about 5.30pm on February 25.

Two other men have been charged in relation to the affray and will front court next month.

Police have not ruled out further charges.
