Witness Frank Bertola said Senator Culleton fell during a fracas outside Perth Magistrates Court on Tuesday morning as One Nation member Anthony Fels was trying to serve him bankruptcy papers.

Mr Bertola said Craig Hutton, a supporter of Senator Culleton who was accompanying him, stood in between Senator Culleton and Mr Fels and tried to prevent the sealed documents being served.

Footage aired by Channel 7 showed Senator Culleton lying on the ground outside court, as Mr Fels drops papers on him.

A young man runs towards Mr Fels, shouting "get off my dad", while another man pushes Mr Fels away.

Senator Culleton then jumps up and removes his jacket, walking towards Mr Fels, saying "don't you ever do that to me".

The two men are kept apart by two of Senator Culleton's supporters.

A spokeswoman for Senator Culleton said he had been discharged from Royal Perth Hospital and was recovering at home.

She said the senator had injured his wrist but it was not broken.

She said Senator Culleton planned to hold a press conference on Wednesday to discuss the incident.

Bankruptcy case continues to dog Senator Culleton

Mr Bertola said he was seeking to have Senator Culleton served with a bankruptcy petition that lists a further 40 creditors allegedly owed money by Senator Culleton.

In December, Senator Culleton was declared bankrupt by the court and he faces being barred from serving in the Senate.

Mr Bertola said the men were "shouting and carrying on" and Senator Culleton's son William was also involved.

He said Senator Culleton and Mr Hutton both fell over during the incident and Mr Fels dropped the papers on them and walked off.

"Craig Hutton pushed in between again and Craig and Rodney fell to the pavement," Mr Bertola said.

"And with that Anthony was in a position to drop the documents on Rodney and say 'You are served'."

"I could tell Rodney wasn't going to take service easily, he made efforts to duck and dive one way or another ... but touching someone with a sheet of proper paper is not considered to be an attack. They lost their footing.

"Anthony is a wise enough person not to engage in any violence and he was only affecting a proper process."

Mr Fels, a former WA Liberal MLC, has been contacted for comment.

A spokeswoman for Pauline Hanson said it would be inappropriate to make comment on the circumstances surrounding Mr Fels' involvement in the incident, as it was not relevant to the party.

She said Mr Fels has applied to be a candidate of Pauline Hanson's One Nation Party, however he had not yet been endorsed.

Culleton in court seeking restraining orders

A spokeswoman for Senator Culleton confirmed he was leaving the court when a man approached him and he was injured.

She said Senator Culleton had been in court seeking a permanent restraining order against Mr Bertola and another man, Bruce Bell.

She also told the ABC the Australian Federal Police had been in touch to check if Senator Culleton needed additional security.

Mr Bertola and Mr Bell were arrested after being evicted from a bankruptcy hearing involving Senator Culleton in the Federal Court in Perth last month.

A WA Police spokeswoman said officers had been called to the Kings Hotel near the Perth Magistrates Court to attend an incident at 10:40am, but when they arrived no-one was there.

She said it was understood a man involved in the incident had been conveyed to Royal Perth Hospital, but no-one had been taken into custody.

She said enquiries were continuing.

Senator Culleton resigned from One Nation on the same day as his bankruptcy hearing in December after a series of public spats with party leader Ms Hanson.
