Local group Stirchley is For Everyone, made up of residents and business owners, said the night of “targeted violence and hospitalisations” marked a “dangerous escalation”.
They said they had faced months of “harassment, doxxing, and intimidation” from the group and urged Birmingham Selly Oak MP, Al Carns, to help.
“Despite consistent pleas from the community for intervention, residents feel they have been left to face this far-right aggression alone,” a statement said.
Defence minister Carns, who is thought may run for the Labour leadership as a potential successor to Keir Starmer, condemned the violence in a post on X, external.
“I am seriously concerned by reports of intimidation and violence in Stirchley yesterday and have written to the West Midlands Police to highlight these issues,” he wrote.
“The union jack is a symbol of unity, not division, of patriotism, not polarisation. I condemn all attempts to hijack our flag and sow violence in our communities for political gain.”
