The South London rapper, real name Blaine Cameron Johnson, died following a car accident while travelling to a gig at Keele University, police confirmed.
A statement said: "Blaine Cameron Johnson, 28, of London, died after the Toyota Prius he was travelling in was involved in a collision with a Vauxhall Combo van at 1.30am. He was pronounced dead at the scene."
Cadet signed a services deal with Absolute in 2016 and was represented by Primary Talent International.

The track has more than 19 million streams on Spotify, where Cadet has over 1m monthly listeners. He released 10-track project The Commitment 2 in 2017, via his own Underrated Legends imprint.

If it wasn’t for artists like Cadet & Novelist pushing the word about my studio & coming week after week, I’d never have been able to quit my job when I did.

Look at what everyone is saying about you, I proper don’t even know what to type this feels mad weird. I was gonna write a long speech about how I met you and what you’ve done for me but where does man start. Everyone loves you look at what everyone has to say about your heart and character. This guy ALWAYS, as in literally every single time I see him greets me with a “I love you lil bro”, the last few times we’ve seen each other that’s all we say, we haven’t even caught up, man just sees you and you say you know I love you lil bro and I say bro from early I love you. This guy has saved my arse when I was dead broke and made it a duty to let me know you’ve got my back, like that’s all you say and remind me. IThis man exudes love. I can’t even explain how clean hearted you are, look what you mean to everyone. No one will ever forget you big bro, words can’t do anything justice right now but rest in peace to the absolute REALEST and I can say that with my hand on my heart. Love you bro ????????????????
Waking up to the terrible news that Cadet has passed away. I can’t believe it. Such a talent, and a lovely guy, always smiling, infectious energy. My thoughts are with his family, and close friends at this time. ????????— Grime Kids OUT NOW (@DJTarget) February 9, 2019
