In a bid to cover up their shirts, he and one of his sons had jackets but his other son did not.
“[We] kept on walking down and then another group came on from across the street and again you could see they were trying to get to one of my sons,” he said.
“As a dad, I had to step in and push them away. We did not throw any punches, but it was a really dangerous situation.”
He said they called the police and, as the “groups were still nearby”, they were able to point them out to officers.
“They did not stop to speak to any of the groups and they walked off,” he said.
“We spoke to the officers and [they] told us to: ‘keep walking through safer routes’ and left us.”
Neighbourhood Insp Chris Green, from Avon and Somerset Police, said: “This is an awful incident which will have caused significant distress to the victims but, thankfully, they did not suffer significant physical injury.”
A spokesperson for Avon and Somerset Police said: “We remain in contact with the victims and have carried out several enquires as part of our ongoing investigation. “
