A soldier who was jailed for six years for strangling a woman in East Sussex with the intention of raping her as she walked away from a railway station has had his appeal against his conviction and sentence rejected.
Trevor Clark, 22, was staying in Bexhill when he attacked the 18-year-old woman, who was a stranger to him, in New Park Avenue at 3.40am on August 19 2012, Sussex Police said.
He was arrested six days later and found guilty of strangulation with intent to rape following a two-week trial at Lewes Crown Court in August last year.
Clark was also told he would be on licence for four years after his release and was placed on the sex offenders register for life, a police spokesman said.
He appealed unsuccessfully against his conviction and was refused leave to further appeal against that decision, police said.
Clark also appealed against the period of his extended licence, which was also rejected by the Court of Appeal.
