Policeman 'Dancing Dan' lights up Notting Hill Carnival

A video of a cop popping and locking at a British festival has given a London police officer a second brush with fame.

The officer was spotted getting into the spirit of the Notting Hill Carnival, an annual event celebrating Britain's West Indian community, by an MC on stage.

"We got a policeman over there with some moves," the MC says.

"Make some noise for the undercover raver."

Twitter user @phemmynice shared a video of the officer's antics, and he was quickly identified as Police Constable Dan Graham.

The officer, from Kingston in London's south-west was dubbed 'Dancing Dan' after appearing on Britain's Got Talent earlier this year.

Despite being eliminated in the semi-finals, he became a social media star, gaining massive support from his fellow officers.

PC Graham has since maintained a profile on social media, often sharing snaps of his dancing and policing duties.

A video of his Notting Hill routine, shared to his Facebook page, racked up more than 300,000 times in 24 hours.
