This is the moment police ordered members of the public to stop sunbathing as they warned that the coronavirus lockdown is "not a holiday".
The officers filmed themselves telling people relaxing on Shepherd's Bush Green in west London to "go home".
On Monday, Boris Johnson said tougher restrictions would be enforced on people’s movements and warned those ignoring them would be fined.
Officers will have powers to disperse gatherings under a ban on meetings of more than two people apart from those who live together.
