A teenage violin prodigy was found dead at her father’s Kensington mansion amid warnings of a new “calvin klein” drugs craze.

Katya Tsukanova, 17, one of Britain’s leading young musicians, died from a suspected overdose only days after giving a concert at the Royal Opera House.

On Thursday night her devastated father Igor, a millionaire philanthropist, revealed how he found Katya’s body at the family home after she returned from partying with friends.

“My daughter was so happy, and she had such a bright future,” Mr Tsukanov told the Telegraph.

“She was such a smart girl, and she made one bad choice. What can we parents do? The children will do what they want anyway, and they never tell you the truth.”
