Herve bragged he was a “general” in one of the most feared gangs in London, responsible for scores of stabbings, shootings and robberies.
Herve, 24, goes by the gang name Zeltor. In 2009, he wrote on a Bebo profile page: “General Zeltor on dis ting say no mre.”
And in a chilling reference to gangland violence, he posted: “All u aluminium gangsters coverd by other peoples fame, u knw hu u r, get real. level has changed. my TEAM DO, DID AND THEY F****** DOES THIS THING. so n***** please, cos u dnt wanna see my n*****s squeeze, cos if we do we leave ur f****** body ina fridge, let it freeze...let it go six feet deep...bigup my up all my DSN mandem say no mre.”
DSN rose to notoriety in 2007 after a pitched battle took place at a shopping centre in Croydon, South London.
Members fought with a rival gang in broad daylight using machetes and bats as shoppers looked on horrified.
Dozen of stabbings around the area have been linked to the thugs along with a string of shootings.
In July 2012, Herve received a 12-month conditional discharge for criminal damage after launching a paving slab through a car window while a woman sat at the wheel.
He was also ordered to pay £100 compensation, £100 to the victim and £80 court costs.
