Andrew Walker from Norwich has been jailed for three years after being convicted of rape.
Detective Inspector Ross McDermott of Norfolk Constabulary's Rape Investigation Unit, said:
Walker was arrested in May 2012 when he returned to the UK after a short period abroad.
Despite the offence having taken place nearly three years ago, a meticulous investigation has enabled this offender to be brought to justice.
"Hopefully the verdict will give other victims of previously undisclosed similar crimes, the confidence to come forward and report matters to us.
"They can be safe in the knowledge that we will fight relentlessly for the truth and for justice not just for the victim, but also for the safety and protection of the wider public.”
A Norwich man has been jailed for three years for rape - thanks to forensic evidence.
Andrew Walker, 27, of Newbegin Road, was sentenced to a total of 40 months in prison and placed on the Sex Offenders Register for life.
Walker was sentenced at Norwich Crown Court today after previously pleading guilty to the two counts of rape.
The incident took place in Norwich in May 2010 when the victim, aged in her 20s, had been for a night out with friends. She reported the attack to police and agreed to a medical examination.
As part of the investigation DNA evidence was obtained which assisted detectives to build a case against Walker who was finally charged with the two counts.
