A man has been arrested and charged with raping a 10-year-old girl at a reserve in Adelaide's north earlier this month.
The 29-year-old man was arrested at a northern suburbs home last night by detectives from the Special Crime Investigation Branch.
Police said the man approached the girl at the Blair Athol Sports Community Club on April 3 and assaulted her in a toilet block, leaving the scene before officers arrived.
He has been charged with two counts of rape, aggravated indecent assault, gross indecency and unlawful detention, and will appear in the Adelaide Magistrates Court today.
Police previously said the man confronted the girl while she was on the playground, about 6:00pm, before luring her into a toilet block.
"Any sexual offending against a child is abhorrent. It's very, very serious," Chief Superintendent Mark Wieszyk said.
"The victim has displayed incredible courage during this investigation.
"The best way to describe her was very courageous in being able to provide the information we could act on.
"Detectives did a lot of work, followed a lot of investigational leads, which led to this person but I can't go into any more detail than that because of the processes at the moment."
Public thanked for assisting police
The arrest follows an intensive campaign by police to identify a suspect, with officers carrying out doorknocks in the area.
Last week, Senior Sergeant Graham Tomkins said police would allege the man's offending was "at the highest end of sexual assault".
"Detectives have worked tirelessly on this case since it was reported," he said.
"This girl is remarkably brave … she has constantly amazed the senior detectives involved in the case.
"She gave a stoic account of what happened to her."
Police earlier released CCTV footage of a man entering and leaving the park around the time of the assault.
They have thanked the public for assistance provided, and said 58 calls had been made to Crime Stoppers about the incident.
But they have urged anyone else with additional information to contact them on 1800 333 000.
