A Black Lives Matter protest in London was overshadowed after clashes broke out in Downing Street which saw 13 people arrested.

Although demonstrations were largely peaceful, a scuffle broke out between some protestors and the police in Westminster resulting in arrests, reports Mirror Online.

Yesterday's protest started off in Hyde Park and was attended by thousands of people in support of the Black Lives Matter movement.

The movement gained recent momentum following the killing of George Floyd, a black man who died at the hands of the police last week.

But despite the majority of protestors peacefully demonstrating, it was marred by tense scenes outside Downing Street later in the day.

In one incident an officer is understood to have been punched in the face with two men detained on suspicion of assaulting an emergency worker.

And as Boris Johnson was speaking at the daily coronavirus press conference, videos shared on social media showed protesters and police clashing outside Downing Street.

Footage showed objects including signs and a traffic cone being thrown at police while one protester could be seen being wrestled to the ground and restrained by officers.

Freelance journalist Mattha Busby filmed the moment and said it was "unclear exactly what started things".

"Police appeared to attempt to take a man from the crowd and pandemonium ensued," he tweeted.

At one point, police escorted a man to the side of the road who was bleeding from the head, with blood over his clothes and camera.

A crowd followed a group of officers to outside the Foreign and Commonwealth Office - which had been daubed with "BLM" in black paint - where protesters shouted "answer for your crimes" and "no justice, no peace".

Plastic and glass bottles were thrown in the direction of officers and protesters pulled down a line of temporary barriers outside Downing Street.

Officers formed two lines and rested their batons on their shoulders, shouting "get back" at protesters as they separated the crowds.

A police spokesman later confirmed a total of 13 were arrested during the policing operation for protests in Westminster, which ran beyond 2am on Thursday.

Star Wars actor John Boyega was among those to speak at the rally before protesters, many wearing masks and holding placards, marched on Westminster.

Some officers were seen "taking a knee" earlier in the day, but when protesters knelt at 6pm no police joined them.

Wednesday's demonstration was triggered by the death of unarmed black man George Floyd.

The 46-year-old died after a white officer held him down by pressing a knee into his neck in Minneapolis on May 25, sparking days of protest in the US.

Police added that social media rumours The Cenotaph had been damaged during the protests were incorrect and that they "were not aware of any damage".

Prime Minister Boris Johnson said he was "appalled and sickened" to see what happened to George Floyd, while chief constables from across the UK issued a joint statement saying they "stand alongside all those across the globe who are appalled and horrified".

In the US, protests began in Minneapolis where George died and quickly spread across the country.

Major demonstrations have taken place in areas including New York, Los Angeles, Miami, Columbia, South Carolina and Houston.

Some have included clashes between police and protesters, including the use of tear gas and rubber bullets by officers.

Ex-Minneapolis police officer Derek Chauvin now faces a second-degree murder charge over the death of Mr Floyd after he was initially charged with the less serious third-degree murder.

And three more US police officers are to be charged aiding and abetting murder in relation to the incident after they were caught on camera appearing to do nothing to stop Mr Floyd's tragic death.
