Betty Carter and Richard Goldsmith have told NITV News they are seeking legal advice about whether to lodge a complaint against police.

The couple were minding seven children when police came to their home and told them they were being arrested for the kidnap of a nephew. But they say they weren't charged with kidnapping, only offensive language and disorderly behaviour.

Footage of their arrest was filmed on a mobile phone and has been widely viewed online.

"They had me up against the wall there, they threw me down here then dragged me down these stairs and the other stairs," Mr Goldsmith said.

Mr Goldsmith has epilepsy and says he feared the stress of the arrest could've brought on a fit.

"My missus told them I take seizures and that, when they could have used different force to apprehend me," he said.

They say the children were frightened.

"They looked at the police as good men, now they look at them as bad," Betty Carter told NITV News.

The Aboriginal Legal Rights Movement is calling for police to be better trained and to use arrest as a last resort, saying it's not just children who feel frightened.

"I think for the community there's still a pretty poor relationship with police, and particularly a lot of interactions with police particularly at times when they might be going through and doing raids and a lot of our grandmothers, a lot of our grannies in particular complain about the way that they're treated at that time," said Cheryl Axelby, of the Aboriginal Legal Rights Movement.

NITV has put a series of questions to South Australian police, who responded that the circumstances of the arrest are currently being reviewed.

Another video has emerged of the arrest of a young teenage boy with his arm in a cast showing him pinned down for more than 10 minutes during an arrest by at least five police.
