Police officer Daniel Graham took time out of policing London's Notting Hill carnival on Sunday (August 27), to stun crowds with his dance moves.
In a video that went viral online, Police Constable (PC) Graham can be seen dancing before the DJ calls him an "undercover raver".
The crowd cheers as he gives one person a high five after showing off his moves.
Graham has shown his talents to the public before, reaching the semi-finals of television talent show Britain's Got Talent this summer.
The three-day Notting Hill carnival celebrates Afro-Caribbean culture in what has become Europe's biggest street festival.
