Tributes have been paid to a teenager who died following a knife attack at a gathering.

Charlie Cosser, also known as ‘Cheeks’, sustained multiple stab wounds during the incident in Marches Road, Warnham, West Sussex, in the early hours of Sunday 23 July.

The 17-year-old, from Milford in Surrey, was taken to hospital, where he died on Tuesday 25 July.

His family – dad Martin, mum Tara, older brother Adam and younger sister Eloise – said in a statement: “Our lives have been destroyed by the tragic and unnecessary loss of our son. Despite courageously battling right till the very end of his young and innocent life, his injuries were too severe and he tragically passed away on the evening of Tuesday 25 July.

“He was the most caring, cheeky, loving son and brother we could have ever wished for, and we cannot imagine a life without him."

They continued: “Charlie’s wider family are deeply shocked and saddened by the sudden loss. His grandparents, aunts, uncles and cousins are struggling to come to terms with this tragic event.

“Tributes have been pouring in from Charlie’s wide circle of friends which we would like to acknowledge have brought us huge comfort in our darkest hours.

“We would also like to thank on our and Charlie’s behalf, all of the efforts of the emergency services who treated him on the scene, as well as the whole of the critical care team at the Royal Sussex County Hospital in Brighton, who did absolutely everything they could to save our precious boy, with the upmost compassion, empathy, sympathy and care.

“His ridiculously silly sense of humour will be deeply missed by everyone that knew and loved him.”
