Families and office workers enjoying the last of the evening sunshine scattered as more than a thousand teenagers fought running battles with riot police along the banks of the Serpentine, a few hundred yards from Kensington Palace, Standard UK reports.
The mob was driven back to Marble Arch where around 500 remained until midnight, hurling bottles at the ranks of police and chanting “Black Lives Matter”.A breakaway group stormed a nearby branch of McDonald’s, causing terrified staff to flee downstairs as dozens of teenagers leapt over counters to clear the racks of food.
Buses were diverted from the streets around Park Lane, which was littered with shattered glass, as the last remaining youths were detained or dispersed.
Two officers were rushed to hospital during the melee, one with stab wounds the other suffering head injuries after being struck by a bottle.Riot vans blocked off Oxford Street to prevent the crowd from spilling into the world-famous shopping district.
At least two other teenagers were taken to hospital with stab wounds.
