A man who runs a parody Twitter account of the Queensland Premier has been arrested for allegedly pushing Liberal National Party volunteers on the campaign trail in Brisbane.

The 44-year-old man, who goes by @Can_Do_Campbell on Twitter, was wearing a T-shirt reading "I'm with stupid" when he allegedly heckled the volunteers in Fortitude Valley about 8:30am (AEST).

Labor candidate Grace Grace had been campaigning on the street about 20 minutes before, but her competitor, LNP MP Robert Cavallucci said it was his volunteers who were targetted.

"It was my volunteers who were harassed and pushed," he said.

Queensland Labor senator Claire Moore, who was campaigning across the road, said the accused was standing on the street corner with LNP volunteers, waving at traffic.

She said at no time was there any violence or anything that should have raised alarm.

Three cars, a paddy wagon and about a dozen police turned up.

Senator Moore said one of the officers said he had received two complaints.

"There was no threat, there was no danger to anyone," she said.

"It was absolutely an over reaction.

"I saw some light-hearted laughing and pushing but it never crossed my mind that this was a serious incident."

The man was taken to the Brisbane watch house and charged with public nuisance but later released.

He is due to appear in court early next month.

In an exchange on Twitter Ipswich Councillor Paul Tully urged Police Commissioner Ian Stewart to rein in officers.

Cr Tully asked for no arrests to be made during the election campaign unless there was a breach of peace.

But Commissioner Stewart did not agree.

"We take appropriate action if individuals break the law," he wrote on Twitter.

"Court decides the lawfulness and consequences.

"Our focus - keep u safe."

Fake Campbell Newman light-hearted after arrest

@Can_Do_Campbell is a prolific satirical tweeter on politics, having amassed some 7,100 followers.

After he was released from custody, he appeared to be in a light-hearted mood: "Currently ironing my best plain white shirt".

When he started his Twitter profile in 2010, he originally went to great lengths to hide his identity and even turned up to an interview with the ABC in 2011 wearing a balaclava and dark sunglasses.

At the time he said he was not associated with any political party but found it amusing to comment on now Queensland Premier Campbell Newman, and claimed he had sources inside council and the state LNP .

"To show another side of someone who is very well controlled and who has a large PR team around him, that manages that image," the alleged offender said in 2011.

Ms Grace won Brisbane Central after the 2007 by-election and held it until the 2012 election, when she lost to Mr Cavallucci.

Mr Cavallucci holds the seat by a 4.9 per cent margin.
