A family row is believed to be behind a mass brawl in the Earlham area of Norwich on Sunday evening in which nine people were arrested.
Police were called at 7.25pm following reports of a disturbance on Motum Road involving a group of up to 30 people.
A 17-year-old girl, a 29-year-old woman, and seven men aged 19, 27, 28, 32, 33, 36 and 38, were all arrested on suspicion of violent disorder and remained in police custody on Monday morning.
Inspector Nick Paling said: 'This was a large disorder involving a group of people who are known to each other; however, officers have increased patrols in the area today to offer reassurance to local residents.'
A video posted on Facebook shows part of the disturbance. One man is carrying a metal object in his hand and police officers can be seen restraining people, while onlookers shout.
Another video taken on Snapchat shows eight police cars on the road with the person who posted the video commenting that there were more then 25 police cars at the scene.
