CANBERRA -- Key One Nation adviser Sean Black has been arrested and charged in Brisbane with numerous serious assault offences.

Black, a media and policy adviser to Queensland senator Malcolm Roberts and former Logan City Councillor, was taken into police custody late Wednesday morning.

The 39-year-old has been charged with three counts of common assault and three counts of assault occasioning bodily harm, police confirmed to HuffPost Australia.

The whole of the case cannot be revealed for legal reasons.

Fairfax Media reported last year that Black was under police investigation after complaints were made in August 2016.

These complaints and subsequent reporting have been dismissed by Malcolm Roberts as "fake news".

"While it's terrible that Pauline and I are subjected to lies and smears to try and discredit us politically, it's totally unacceptable that when they can't find dirt on us the media go after our staff," he wrote on Facebook in February.

"I have been working closely with Sean for the past five months and he is a great asset to our team and to Pauline's team, both as a hard working aide and as a personal friend.

"Sean has my full support and will continue to have my full support in this office for as long as I am an elected official."
