A rap battle between two rappers and a fake "popo" in Lewisham has become an internet sensation.

Two rappers have appeared in a video on YouTube channel Trollstation, battling a "police officer" on Lewisham High Street.

After dropping dead bars about not being able to afford to go shopping on Lewisham High Street, the pair are interrupted by two men dressed as police officers.

One of the police officers then claims to "spit bars" and takes over the microphone.

He rapped: "I'm gonna cancel the back-up and come through, what you saying what you gonna do?"

The fake policeman then becomes offended by one of the rappers who said: "You're Mum is a pig, you're Dad is a pig, you're Uncle's a pig, everyone's a pig, look at your face man you look like a pig."

He then handcuffs the rapper and appears to arrest him.

More than 50,000 people have watched the prank video on YouTube.

A Metropolitan Police spokesman confirmed that men in the video are not police officers and there are no offences committed in this video.
