British model Katie Piper had a look and a life that foretold a seemingly bright future. But the 24 year old's dreams were destroyed when a complete stranger threw sulfuric acid in her face on a London street. The thug who disfigured Katie Piper in an acid attack has applied for parole. Stefan Sylvestre, 27, aims to convince officials he poses no risk to the public after six years in jail. Katie, 31, spoke last year of her horror at the prospect of him being released. And a justice campaigner said tonight. The acid attack thug who left Katie Piper scarred for life could be freed soon after serving just eight years of his sentence. Stefan Sylvestre, 27, was jailed indefinitely in for throwing acid in Katie's face on the orders of her obsessed ex-boyfriend. However, having served the minimum term.
