Hyde Park McDonalds is ransacked in just seconds by a group of Black Brits.Five people - including a police officer - were stabbed last night during a night of violence in three different parts of London yesterday evening. <br /> <br />A Metropolitan Police officer and two members of the public were knifed and four other PCs were injured after a water fight and party in Hyde Park spiralled out of control in the city's worst bout of violence since the 2011 riots. <br /> <br />Meanwhile two 16-year-old boys were stabbed at a separate water fight in Burgess Park, Southwark, while police attempting to shut down an illegal block party in Stamford Hill, Hackney, had bottles thrown at them. <br /> <br />Grainy footage has emerged of a young man, who has not been named, apparently being set upon by three others in the middle of a busy road near Hyde Park as buses, taxis and cars are forced to swerve around the attack. <br /> <br />In the footage, which was posted on social media, a youth wearing a white t-shirt appears to repeatedly thrust a weapon at another young man, who is on the floor grappling with two attackers, before all three run off as onlookers scream in horror.
