The Queensland Police Service is refusing to release information about incidents involving the excessive use of force by officers in the Brisbane City Watch House, saying it would be "contrary to the public interest".

Key points: QPS said the documents were being used by the Crime and Corruption Commission's (CCC) investigations

The QPS also rejected the ABC's Right to Information request on the grounds that the relevant documents "have and continue to be utilised" by the Crime and Corruption Commission (CCC) for its assessment of complaints and "subsequent investigations".

But the CCC has told the ABC it has no ongoing assessments or investigations relating to incidents involving officers in the Brisbane watch house.

The QPS revealed in June that two watch house officers were being investigated over allegations they used excessive force on a 16-year-old boy in the Brisbane watch house in May.

The two officers, aged 52 and 41, have been suspended from the police service and the investigation is ongoing.

In May, Four Corners revealed that children were being held in watch houses in isolation, sometimes for weeks, with some forced to wear a so-called 'suicide smock'.

The program also reported that one girl had part of her finger severed in a cell door.

In June, the ABC applied to the police service for documents regarding use of force by watch house officers inside the Brisbane watch house over a three-month period.

After missing several statutory deadlines, the QPS wrote to the public broadcaster refusing access to all documents.

One of the reasons for the rejection was that the documents contain "information the disclosure of which would, on balance, be contrary to the public interest".

The police service ruled that the information could identify people, despite the fact that many Right to Information releases redact the names and personal details of individuals.

The QPS also refused to release information on the basis that it was or could be part of a CCC assessment and would comprise information "involving possible or suspected misconduct".

But the CCC has told the ABC that it "has no matters currently under assessment or investigation relating to the conduct of QPS officers at the Brisbane City Watch house" for the period in question.
