Rioting and disorder in the UK has now lasted for a week, with unrest witnessed across England and parts of Northern Ireland.
Police were injured during “sustained violence” in Plymouth on Monday, while similar trouble on the streets of Darlington saw officers pelted with bricks.
Six people have, meanwhile, been charged in connection with riots outside a hotel in Rotherham on Sunday, which was being used to house illegal immigrants.
Justice minister Heidi Alexander said the government will bring more than 500 additional prison places into use to deal with rioting, and some 6,000 specialist police officers were at the ready.
Extra cells at HMP Stocken in Rutland will be in use from next week, Alexander said, with plans to also use space at Cookham Wood Young Offender Institution in Kent for adult prisoners.
She also revealed more detail about the planned “standing army” of police officers Prime Minister Sir Keir Starmer announced on Monday afternoon.
Alexander told Times Radio: “These are police officers who have had specialist training in dealing with public order offences.
“We had 4,000 available at the weekend. There will be another 2,000 available this week. It also means that police officers are able to be deployed in parts of the country where they are needed most.”
Elsewhere, she said courts could begin sitting “through the evening, the night, at weekends” in order to swiftly prosecute rioters.
In Plymouth on Monday night, “several officers” suffered minor injuries and two members of the public were taken to hospital, according to Devon and Cornwall Police.
Durham Police said one person has been arrested after bricks were thrown at police during violent disorder in Darlington on Monday evening.
The force said Section 60 and 60AA powers have been authorised in the area, giving officers enhanced stop and search capabilities and the authority to order people to remove face coverings.
Following the disorder, Durham Police Assistant Chief Constable Richie Allen said, “What we have been dealing with tonight in Darlington has been sporadic pockets of violent disorder involving groups of people intent on causing serious harm to our communities and their property.”
Disorder continued in areas of Belfast, Northern Ireland, while, in Birmingham, Sky News reported that one of its vans was attacked by a “knife-wielding man” on Monday.
The channel said its journalists had observed “a large gathering of Muslim men” who were preparing to “defend” the street from a rumoured far-right protest in the area that never materialised.
Social media footage later showed a mob waving Palestinian flags attacking a pub in the city and smashing windows of cars as they marauded through the streets.
South Yorkshire Police said said six people have been charged with offences following rioting outside a hotel in Rotherham on Sunday.
The force said they are due to appear at Sheffield Magistrates’ Court on Tuesday morning.
In the west of England, Avon and Somerset Police said a third man has been charged in connection with violent disorder in Bristol city centre on Saturday.
In the northeast, Cleveland Police said a total of 28 people are due to appear at Teesside Magistrates’ Court charged with violent disorder and other offences following violence in Middlesbrough on Sunday.
The force said the court had set aside a remand court to deal with those appearing on Tuesday.
There have been at least 378 arrests since the violence broke out last week, with the National Police Chiefs’ Council saying the total is expected to rise daily.
In Southport, where the fatal mass stabbing which sparked much of the unrest occurred on July 29, hundreds attended a peaceful vigil on Monday evening in memory of Bebe King, Elsie Dot Stancombe, and Alice Dasilva Aguiar.
Children blew bubbles and others left flowers and heart-shaped balloons in remembrance of the victims of the stabbing attack at a Taylor Swift-themed holiday club.
Merseyside Police have said one child caught up in the incident remains in hospital but all other patients have been discharged.
Axel Rudakubana, a 17-year-old from Lancashire who was born in Cardiff to Rwandan parents, has been charged with the murders.
