KEY One Nation staffer Sean Black has been arrested by detectives in the latest scandal to engulf the party this week.

His arrest follows explosive tape recordings released revealing party figures discussing ways to “make money” out of the state election.

Black, 39, a senior adviser to Queensland One Nation Senator Malcolm Roberts, was taken through the Roma Street watch-house just before noon yesterday. He had flown into Brisbane from Canberra on Tuesday night.

He is facing a number of historical charges, three counts of common assault and three counts of assault occasioning bodily harm assault, but The Courier-Mail cannot publish more details for legal reasons.

Complaints were made to the Queensland Police Service late last year.

Black was one of the early recruits to One Nation Senate staff when they were swept to power in last year’s election, taking up his position in September.

He appeared before the Brisbane Magistrates Court yesterday afternoon, where it was revealed some of the allegations dated back to 2007.

Magistrate Jacqueline Payne granted him conditional bail after police did not oppose his release.

“He is planning to travel to England in September,” the duty lawyer added.

“His new partner is English and they’re planning their wedding in September in England. They’re in fact married but having a wedding celebration in September.” The case will return to court on June 19.

Black made no comment to reporters as he left.

A spokesman for Senator Roberts said it was a difficult time for the office and that no comment would be made.

Senator Pauline Hanson’s spokesman said it was inappropriate to comment while the matter was before the court.

The former real estate agent has a long and colourful history in politics.

Mr Black was a Logan City Councillor for four years, from 2008, and was previously married to fellow councillor Hajnal Ban.
