The thug who killed an innocent bystander in High Wycombe in the UK’s first acid attack death was a member of a notorious drill gang, it has been reported.

Xeneral Webster, 19, admitted the manslaughter of Marlow dementia nurse, Joanne Rand, and was jailed for 17 years in July following the horrific attack in Frogmoor, which left the 47-year-old with serious burns.

The mother-of-three died from blood poisoning 11 days after she was struck with a bottle containing highly-concentrated sulphuric acid on June 3 last year.

It has now been claimed that the killer – who had the street name General - was part of the 12 World rap gang, based in Shepherd's Bush in west London, which has a long-running feud with the rival 1011 gang.

Webster, who had himself been attacked with acid in the past, was known for “rolling around the estates” with a machine gun, The Sun has reported.

A source told the newspaper: “General was well-known for rolling around the estates with his mac gun - that became his thing.

“He was always in trouble and even battling with older gang members of 12 World - which is how he got attacked with acid in the past.”

Another source, close to Webster’s family, told The Sun they blamed drill music for his life of crime.

Drill music is a form of hip hop that first originated in the South Side of Chicago. It features violent, dark lyrics and focuses on crime and life on the streets and the style became popular in the UK in 2012.

Music videos posted online often feature masked gangs threatening each other, with lyrics about drugs, guns and stabbing rivals with knives.

The source said: "Drill music is a problem. These kids all think they can make their money from hits on the Internet. They see music and drugs as the only way to earn a living.”
