A teenager was knocked unconscious, another man taken to hospital and two others injured after three brawls broke out in the Narrabri CBD on Saturday night.
And police are looking for a man dressed for a night out as a result of two of them.
Inspector Robert Dunn, of Narrabri police said three of the injuries were sustained in two separate, but related incidents, on Maitland Street, near Bowen Street, from about 9.45pm.
About 12 people were congregated on the eastern side, not far from The Courier building, when some 16-year-olds walked past.
A man in the first group then allegedly verbally abused one of the teenagers on the other side as they were walking away.
The man then continued to taunt the teenagers.
