A police officer was killed when he was “dragged along by a vehicle” while attending a reported burglary.
PC Andrew Harper, 28, who got married four weeks ago, died at about 23:30 BST on Thursday in Berkshire.
Thames Valley Police said 10 males, aged between 13 and 30, have been arrested on suspicion of murder and remain in custody at various stations.
Prime Minister Boris Johnson said the officer’s death was a “mindless and brutal crime”.
Thames Valley Police Chief Constable John Campbell said the death of PC Harper, an Abingdon-based roads policing officer, had left the entire force “shocked and saddened”. He told a press conference that although the cause of PC Harper’s death had not yet been confirmed, he was out of his police car when he was “dragged along by a vehicle”.
A cordon has been put in place at the scene near the A4 Bath Road between Reading and Newbury, at the crossroads near to Sulhamstead. Mr Johnson said the officer’s death was “an absolute tragedy ” and “the most powerful reminder that police officers up and down the country put themselves at risk every single day to keep us safe”. “My thoughts are with PC Harper’s family, friends and colleagues at this terrible time,” he added.
A man has been stabbed outside the Home Office building in central London.
The victim’s injuries are not believed to be life-threatening, the Metropolitan Police said.
Officers were called to the building in Marsham Street, near the Houses of Parliament in Westminster, at 13:06 BST. A man was arrested on suspicion of causing grievous bodily harm. The wounded man went into the building to seek assistance. The building is now in lockdown.
Eyewitness Gareth Milner said he was outside the Home Office when “a number of armed police officers arrived on scene and entered the building”. “Some time later a gentleman with quite a bloodied face and with dressing pressed into his face was escorted out of the Home Office by paramedics,” said Mr Milner. He said the man was “walking on his own two feet”.
A Home Office spokesperson said: “The Metropolitan Police is investigating a knife attack which took place outside the Home Office this afternoon. The victim is receiving medical care.
“This is a deeply concerning incident and our thoughts are with him and his family. “As this is an ongoing investigation. It would be inappropriate to comment further.”
China has condemned violence clashes in the Hong Kong protests as “behaviour that is close to terrorism” – in a sign of its rhetoric hardening.
After days of peaceful protests at Hong Kong International Airport, clashes with police broke out on Tuesday night. Video showed an officer drawing his gun on protesters who beat him with his own truncheon during the disturbance.
It is the second time in a week that Chinese officials have publicly likened the protests to terrorist activity.
Some observers believe that the repeated use of such language suggests that China is losing patience with the protesters, and could increase the likelihood of an intervention from Beijing. However, most analysts consider that at this stage, a direct military intervention is still unlikely.
The former British colony has a special status, with its own legal system and judiciary, and rights and freedoms not seen in mainland China. However, many activists believe this is now under threat.
An armed man has been arrested after stabbing a woman in central Sydney and being detained on the street by members of the public.
A second woman was found dead inside an apartment building on the same street.
“All the information we have at hand would link these two crimes,” police commissioner Mick Fuller said at a press conference. He said the suspect was a “lone actor” with a history of mental health issues. He was known to police but “his history was unremarkable compared to the gravity of the crimes he committed”, Mr Fuller said.The police commissioner said the suspect had some ideologies related to terrorism, but had no apparent links to other terrorist organisations.
It is believed the man had a USB drive containing details of mass killings in New Zealand and the United States.
Mr Fuller said the stabbing is not currently being classed as a terrorist incident but this would be reassessed as the investigation continues.
Three “heroes” were praised by New South Wales Police Minister David Elliot for their role in detaining the man and acting “well and truly beyond the call of any citizen”. He also congratulated the firefighters involved.
The incident unfolded at about 14:00 local time (04:00 GMT) on Tuesday near Clarence St and King St, a busy area in the city centre. Video footage shows the suspect jumping on a car wielding a knife, shouting “Allahu Akbar” and “shoot me”, as another man confronts him with a wicker chair.
