A 50-year-old youth worker says he was assaulted by police outside a venue at Surfers Paradise, in the latest allegation against police on Queensland's Gold Coast.

Ray Currier's allegation comes after CCTV vision of a man being bashed at Surfers Paradise police station in 2012 was leaked by a whistleblower sergeant.

The Crime and Corruption Commission (CCC) reviewed its involvement in the case after a recent complaint from Queensland's Council of Civil Liberties.

Mr Currier, from Drewvale on Brisbane's southside, said police on the Gold Coast sprayed capsicum spray in his eyes and on his genitals, then laughed outside his watch-house cell as he tried to wash it off, after being arrested for what he describes as a tame night out.

He said he still felt "cold fury" at the way he was treated by police.

"It's not like we're a bunch of teenagers - we left that place of our own volition - the footage clearly shows that he told us to move away and that's why we're all moving away," Mr Currier said.

The incident happened in January when Mr Currier and colleagues from the Brisbane Youth Detention Centre were celebrating Australia Day and lending support to a colleague who was recovering from open heart surgery.

Mr Currier said the incident happened about 9:00pm.

CCTV footage shows one member of the group leaving a venue at Surfers Paradise. He was not able to re-enter and the man used his phone to ask police their name and badge numbers.

Mr Currier's colleague was then struck on the leg as police pulled him to the ground where he was handcuffed and marched off.

A short time later, the rest of the group emerges from the venue, including Mr Currier.

Mr Currier, who has worked in youth detention centres for nearly 20 years and has been a Justice of the Peace for 12 years, said he was trying to move the rest of his group on.

"I remember getting hit from behind," he said.

"I also recall being on my stomach ... there was an extreme amount of weight on me.

"I knew I was in a positional asphyxia, which is quite dangerous - we're taught in my role in youth detention - I could feel my panic beginning to rise, which is [also] dangerous in that situation."

The vision appears to show one police officer delivering a blow to his head while Mr Currier is on the ground. Mr Currier said he lost consciousness.

He said a third colleague, who had heart surgery, was also tackled by police and received three broken ribs during the scuffle.

Mr Currier was arrested and put in the back of the police van.

"I'm seething. Bitterly disappointed they didn't exercise any discretion - I can't fathom it," he said.

Mr Currier said when he was in the back of the police van he started singing and that was when he said police got out and sprayed him with pepper spray in his eyes and genitals.

Mr Currier was charged with one charge of assaulting and obstructing police.

Police Service 'not aware' of allegations

The Queensland Police Service (QPS) said in a statement it was not aware of the allegation.

The QPS said due to the matter being involved in court proceedings, it could not comment further.

The statement also said anyone who wished to make a complaint about a member of the QPS could do so by referring to its complaints webpage.

Queensland Premier Annastacia Palaszczuk said it was worrying if the latest allegation was true.

"If that has happened, I am very concerned about it and I am more than happy to have discussions with my director-general to make sure that matter is investigated," she said.

'Absolutely disgusting' treatment

Mr Currier's wife, Kris Currier, became emotional recounting how at 7:00am the day after the alleged incident, her husband walked in and told her he had been arrested.

"My husband's a law student ... he's a Justice of the Peace ... he's done 18 years [working] in youth detention - he's not a troublemaker, he's never had a criminal history in his life," she said.

She said she saw a lump on the side of his head and marks where he had been handcuffed.

"I was shocked," she said.

"He told me ... he was sprayed in the eyes - his eyes were red, they were bloodshot - and then he told me about the pepper spray to his genitals, and how he was still cuffed in the cell. He asked for medical attention - he was refused it.

"He also told me of the officers that were standing outside his cell, laughing at him trying to get water out of the toilet ... refusing to uncuff him so he could get water onto his genital area."

She said when she saw the video footage it made her sick.

"Why hasn't that police officer been charged with assault?" she said.

"If that happened to Ray in his job, he would be investigated. If he did that to a kid in youth detention, he'd lose his job, without a doubt.

"It's absolutely disgusting at how this whole thing has been treated."

She said the incident had had an enormous impact on their family, with Mr Currier unable to work and suffering anxiety and depression.

Mr Currier said two of the group members had laid a complaint at the Coomera police station following the incident but nothing had come of it.

He said he intended taking civil action against the police once the criminal charges, which he would also be fighting, had been dealt with.

Simply comply with police directions, union says

Queensland Police Union (QPU) president Ian Leavers has defended officers for using physical force during arrests, saying they were often left with no choice.

However, Mr Leavers said he could not comment on the alleged latest incident as it was before the courts.

"I believe it goes to court in early February next year, so anything I say on this specific matter, I don't want to be held in contempt of court," he said.

"But what I will say is there are many interactions between police and people behaving in an unacceptable way and it is very difficult to restrain one person.

"From being there myself, it can require three to four people to restrain one person when they are very strong and are affected by alcohol and any other substance."

Mr Leavers said it was best for people to simply comply with police directions.

"If you wish to contest it, go before the courts - but if you wish to put on a turn, and try and assault police or get away from police, they will restrain you," he said.

"It always looks worse than it actually is, so I just think people need to take a deep breath.

"With all the interactions on the Gold Coast, there is a lot of good work being done each and every day and it's easy to take things out of perspective."
