South Australian police have used DNA technology to arrest a man more than 30 years after an alleged sexual assault.
Police say in August 1988, a woman was jogging through Croydon, in Adelaide's west, when she was threatened by a man with a knife before being dragged to a car and sexually assaulted.
She escaped and sought help from a member of the public.
On Friday, police arrested a 62-year-old Paralowie man over the crime.
Special Crimes Detective Chief Inspector Richard Lambert said the arrest proved how far technology had come.
"DNA technology has provided police with increased opportunities to identify people who are responsible for committing all types of crimes," Chief Inspector Lambert said.
"This investigation demonstrates SAPOL's commitment to pursue those responsible for committing sexual assaults, including those that have occurred many years ago.
"The impact of these types of crimes have on their victims is everlasting.
"SAPOL recognises the importance of exploring all lines of investigation to solve these crimes.
"While DNA technology continues to advance, SAPOL will also continue its resolve to make violent sexual offenders accountable for their crimes."
The man was charged with rape and has been bailed to appear in the Port Adelaide Magistrates Court next year.
