London, June 8 : A slave trader's statue in Bristol has been torn down and thrown into the harbour during a second day of anti-racism protests across the UK. It comes after largely peaceful demonstrations across the weekend saw some clashes with police, the BBC reported. On Sunday evening, police in central London issued a dispersal order for the City of Westminster compelling people to leave the area after skirmishes. Prim Minister Boris Johnson tweeted that the protests had been "subverted by thuggery". Thousands of protesters massed for a second day in London, as well as cities across the UK including Bristol, Manchester, Wolverhampton, Nottingham, Glasgow and Edinburgh. Protests were generally peaceful throughout the day, with aerial footage showing thousands of demonstrators flooding the roads outside the US embassy in Vauxhall, south London before marching towards Parliament Square and Downing Street. The Prime Minister later tweeted: "People have a right to protest peacefully & while observing social distancing but they have no right to attack the police. These demonstrations have been subverted by thuggery - and they are a betrayal of the cause they purport to serve. Those responsible will be held to account." Earlier in the day, in Bristol, protesters used ropes to pull down the bronze statue of Edward Colston, a prominent 17th Century slave trader, who has been a source of controversy in the city for many years. Colston was a member of the Royal African Company, which transported about 80,000 men, women and children from Africa to the Americas. On his death in 1721, he bequeathed his wealth to charities and his legacy can still be seen on Bristol's streets, memorials and buildings. After the statue was toppled, a protester was pictured with his knee on the figure's neck - reminiscent of the video showing George Floyd, the black man who died while being restrained by a Minnesota police officer. Home Secretary Priti Patel called the tearing down of the statue "utterly disgraceful", adding that "it speaks to the acts of public disorder that have become a distraction from the cause people are protesting about". "It's right the police follow up and make sure that justice is undertaken with those individuals that are responsible for such disorderly and lawless behaviour," she said. In a statement, Avon & Somerset police confirmed there would be an investigation into the "act of criminal damage". /IANS
