Police were called to two brawls in Masterton on Thursday, one of which was possibly gang-related.
Police were called to Clyde St at about 5.30pm after reports were received of about 10 to 15 men fighting in the street.
Masterton Sergeant Ian Osland said most of the men fled the scene when the police arrived.
It was probable the brawl was gang-related, Mr Osland said.
Later the same evening, at 10.50pm, police were called to outside the Kuripuni Sports Bar where 10 to 15 men were brawling.
Most of the men got into a black van and fled before police arrived, Mr Osland said.
It was not believed the brawls were connected.
No arrests were made at either incident. It was unclear whether anyone was injured.
