West Midlands Police were called out to a vicious mass brawl in broad daylight in Prestbury Road, Aston on Thursday August 15.
A man was thrown to the floor as others threw punches in the disorder.
A video being circulated on social media shows armed attackers with baseball bats, hammers and crowbars used in the fight.
A source close to the family, who did not wish to be named for safety reasons, said: “They came to the address with the weapons and was a ‘revenge’ attack on a family
“Another family tried to take revenge; they came to the family address armed.
“They all had weapons – crowbars, hammers, baseball bats. A man was attacked by six men and suffered a head injury. He’s in a bad way.”
Three men were injured in the fight, including one being hit in the head with a baseball bat.
Two others suffered minor facial injuries, having been punched, West Midlands Police previously confirmed.
It has been claimed the trouble sparked in the middle of the road after one of the victims ‘intervened in another fight’.
“There were kids fighting, they were as young as 14. He intervened to stop the fight and after a couple of days, they came back to take revenge,”
The source continued: “Police have video evidence, photos and addresses of people with weapons, but nothing has been done, no arrests have been made.
“These people are still roaming around.”
The police have confirmed it has yet to make any arrests and is still urging witnesses to come forward.
