Two groups of angry people were charged with assault after a brawl sparked by an argument between a deliveryman and a customer.
The brawl was at a housing estate in Samut Prakan, police said.
About 2pm, a deliveryman on a motorcycle arrived at a house on the estate. He pushed the entry buzzer repeatedly while waiting for someone in the house to come out and accept the parcel he was delivering.
Houseowner Pratichya Thaonoi, 57, finally emerged and angrily asked why he had pushed the button so many times. The man replied he had waited for too long in the hot sun. They exchanged insults. Ms Pratichya was joined by her son.
The deliveryman shouted in the face of her son, "You son of a whore", before leaving on his motorcycle.
The son and deliveryman then each called their friends. The son formed a team of four and the delivery man had about 10 colleagues by his side. The two groups then engaged in a running brawl from one soi to another within the housing estate.
Three people on each side were injured.
Police called to the scene took them all to the station. All were charged with assault.
