A MAN needed hospital treatment following a mass brawl in Abertillery which saw 20 men fighting in the street.
The fight on Saturday night on Station Hill was broken up by nine police officers.
A Blackwood man and another from Trinant were assaulted.
The 21-year-old from Trinant was taken to Nevill Hall Hospital, Abergavenny, with minor facial injuries and was kept in overnight.
Inspector Mark Ryley said 12 men, aged between 18 and 35, were arrested on suspicion of assault and robbery.
Inspector Ryley said they did not know what sparked the fight.
"We don't know what started it at the moment or what led up to it," he said. Inspector Ryley said he would be "amazed" if drink had not played a part in the incident.
