YouTube has removed more than half of the music videos that the country’s most senior police officer asked it to take down because they promote violence.
More than 30 clips have been removed so far.
Metropolitan Police Commissioner Cressida Dick has blamed some videos for fuelling a surge in murders and violent crime in London – and singled out drill music.
She asked YouTube to delete content which glamorises violence.
Drill originated in Chicago. Its biggest breakout star is arguably Chief Keef, famous for his 2012 track I Don’t Like.
The genre’s lyrics often detail vivid accounts of taking drugs and violence.
In February, 17-year-old rapper Junior Simpson was sentenced to life in prison after he and three others stabbed 15-year-old Jermaine Goupall to death.
The court heard he’d penned a track about knife attacks before carrying out the killing.
Giving him a life sentence, judge Anthony Leonard QC told Simpson: “You suggested the lyrics were just for show but I do not believe that, and I suspect you were waiting for the right opportunity for an attack.”
