A man has admitted indecently assaulting a teenage woman at knifepoint during a 200-mile coach journey.
Anthony Gayle, 34, of Thornes Road, Wakefield, admitted subjecting the woman to a sex attack which lasted almost four hours.
The 18-year old victim was travelling from North Yorkshire to London for an acting audition on 19 February when Gayle, a Jamaican aslyum seeker, sat next to her.
Middlesex Crown Court heard that Gayle then threatened her with a penknife and proceeded to indecently assault her over the course of the journey.
On arrival at Victoria Station the victim raised the alarm and police were later able to identify the man from closed circuit television images.
Detective Sergeant Byron Thorne said: "It was sheer terror for the young lady."
Sentencing was adjourned until 26 September and Gayle was remanded in custody.
