Devon and Cornwall Police said 150 officers are deployed in Plymouth city centre and “work is ongoing to de-escalate the situation” after officers were injured during clashes.

In a post on social media, the force said: “We currently have 150 officers deployed in Plymouth City Centre. Violence will not be tolerated, hate will not be tolerated. Work is ongoing to de-escalate the situation.”

Devon and Cornwall Police Superintendent Russ Dawe said “several officers” had been injured in Plymouth and arrests had been made “for a range of public order offences and assaults”.

He said: “We continue to police ongoing events in Plymouth with a highly visible police presence. Specialist officers were deployed to the Guildhall in the city centre at around 3.30pm today. During the evening, we’ve seen levels of violence across the city, and several officers have sustained injuries.

“I would like to reassure the community that we are fully resourced at this time with a strong police presence. Violence will not be tolerated, hate will not be tolerated, and we continue to work with our partners to keep the people of Plymouth safe.”

Asylum seekers who were inside a Rotherham hotel when it was attacked by far-right rioters are frightened but glad to be alive, an activist who attempted to guard the entrance said.

Phil Turner, from Stand up to Racism Rotherham, helped organise a counter-demonstration of around 150 people at the Holiday Inn Express on Sunday in support of the refugees who were trapped inside.

The violence in the South Yorkshire town took place amid widespread rioting across the UK in recent days, in the wake of last week’s stabbings in Southport.

West Midlands Police are investigating reports of an assault and criminal damage to a pub and multiple vehicles after a large group of people gathered in Birmingham.

People gathered in Bordesley, Birmingham, after rumours of a far-right rally circulated online, with footage emerging of masked protesters saying “F*** the EDL, free Palestine”.

Police are also investigating reports of a man who was in possession of an offensive weapon. No arrests have yet been made, the force added.

Six people have been arrested in Plymouth after the far-right and anti-racists clashed amid a wave of mob violence sweeping the UK.

Writing on X, Devon and Cornwall Police said: “We have made six arrests following events in Plymouth today (Monday 5 August).

“During the evening, we saw levels of violence across the city and several officers sustained minor injuries as a result.”

Safeguarding minister Jess Phillips said perpetrators of violence in Birmingham “will face the consequences no matter who they are”.

The Home Office minister, who is the MP for Birmingham Yardley, tweeted: “The police have attended all sites of violence tonight and all those perpetrating it will face the consequences no matter who they are.

“Thanks to all residents who have acted with grace and kindness and have kept people informed so actions could be taken.”

Ms Phillips had reposted text from Birmingham Police’s account, which read: “We have been working hard alongside our community leaders and would like to thank everyone for their support today.”

The MP had earlier written: “People in Yardley are scared tonight. We have directed police to all locations of violence we are hearing about. Any acts of violence will not be tolerated.”
