A 13-year-old boy was one of seven people arrested following a late night brawl which spilled out of a Lancaster city centre pub.
Police were called to The Square, in Great John Street, Lancaster, after a brawl spilled onto the street.
They arrived at the scene at around 11.45pm on Tuesday following reports of fighting and people chanting “The Square” repeatedly.
The fighting is believed to have started inside the pub, and then spilled out onto the street.
It is understood furniture from the pub was thrown about and damage was caused to items inside the pub.
Police say the fighting started when someone was asked to leave the pub.
Four men, aged 21, 34, 41 and 54, and a boy aged 13 and two aged 15 were arrested on suspicion of assault and affray.
All have been questioned and given police bail until November 14.
Investigations are ongoing.
Det Sgt Kev Wright, of Lancaster CID, said: “We are looking at CCTV footage from the night in question. It appears to be a group of people who were in drink, and had started falling out after somebody was asked to leave the pub.
“After an incident like this we do look at the licences of premises involved but The Square is not a bad pub.”
