A video posted on social media appears to capture Boris Johnson taking part in a police raid and being filmed by and speaking to a man already in the property.
The video posted on social media comes after the British Prime Minister attended a police raid on Wednesday with specialist officers near Lewisham, south London.
"Bro, how the f*** did I get raided and Boris Johnson's there," a man says to camera in the video posted online.
The footage then cuts to what looks to be the inside of a home where a man carrying the camera opens a door to find police officers and what appears to be Boris Johnson wearing a form of protective vest and standing just behind the officers.
"Wagwan Boris," the man holding the phone says, which is a form of saying "what's going on" in Jamaican slang.
"Good morning, how are you doing?" Mr Johnson appears to say in response.
No arrests were made during the raid.
The man later told the Independent that he "thought he was dreaming" after waking up to find Mr Johnson in his flat, surrounded by police officers.
Splinter Sales, who described himself as a hip-hop rapper, said he woke up to shouts of "police" outside the property in West Norwood, southeast London.

Mr Johnson joining the police for the raid comes ahead of his resignation, which is due next week.
He has been taking part in a number of visits across the UK, which has been dubbed a farewell tour.
The outgoing prime minister used the opportunity to stress his record on tackling crime.
The visit came after the Telegraph reported that officers are being told to focus on the basics of policing by Home Secretary Priti Patel, with a report by the Policy Exchange think tank warning that the public feel police are being distracted by "woke" causes.
Speaking to broadcasters after the raid, Mr Johnson appeared to defend the police from accusations of being "too woke".
Mr Johnson said: "Look at neighbourhood crime, which is the thing that really affects the quality of life of most people in this country, and it's down by about 38% on 2019 since this government came in.
"I think that's a great effort by the police, not just by the Metropolitan Police, by police up and down the country.
"And what you're seeing is 13,700-odd more police now on the streets. That helps, that makes a difference."
