Police officers involved in the confronting arrest of an Indigenous man in Adelaide, during which footage of him being hit in the back was posted on social media, have been cleared of any wrongdoing.
Police Commissioner Grant Stevens said a series of investigations had determined that the officers had not committed any crime and had not breached the force's code of conduct.
He said it had also been concluded that the arrest of Noel Henry in June was lawful and that charges of hinder police, resist arrest and property damage would proceed to court.
"It will be alleged the body-worn video of one of the officers showed that during the search, the man attempted to break away from police," Mr Stevens said.
"The footage continues to show the ensuing struggle between this man and the police, which lasted for over four minutes.
"Only the final part of the arrest was filmed on the witness's mobile phone.
"At that point, it will be alleged the officers were attempting to handcuff the man, as he was continuing to resist their efforts."
Mr Stevens said during the struggle it would be alleged the man attempted to grab the officer's pepper spray.
He said in response, an officer struck the man between the shoulder blades before trying to move his arm into a position to allow his wrists to come together.
The commissioner said the anti-corruption section investigation had determined the officers acted reasonably and in good faith in the circumstances and had not committed any criminal offences.
The arrest made headlines at the time as it came amid national protests and rallies surrounding the Black Lives Matter movement.
