Police are investigating a potential link between two assaults at two conservation parks in the foothills of the Mount Lofty Ranges.
A young woman was attacked on a running track in Anstey Hill Recreation Park on Friday 3 July following a similar assault at Morialta Falls on Saturday 20 June.
The victim from the most recent attack, Jessica, has come forward to tell her story.
The 26-year-old said she was walking along the Yellowtail Loop through Anstey Hill around 9.30am when a man allegedly grabbed her and pulled her to the ground.
She managed to get away but had no mobile reception so had to run for at least 10 minutes before she had enough phone signal to call 000.
"The woman was able to run away but sustained a cut to her leg," police said.
"She was taken to Modbury Hospital for treatment."
With assistance from Park Rangers, police conducted a search of the area. A short time later, police located and arrested a man in a car park close by.
A 51-year-old man from no fixed address has been charged with assault. He was bailed to appear in the Adelaide Magistrates Court on 4 September.
Jessica is calling for the installation of emergency phones and markers along the trail.
Police are investigating any links to a similar incident at Morialta Falls on June 20, and have asked anyone who witnessed the attack to contact Crime Stoppers on 1800 333 000 or online.
