Military authorities in Denmark have launched an investigation into claims that an army intelligence officer working in Iraq mistreated prisoners.
There have been a number of cases of prisoner abuse
A statement by the military command said the officer, who has not been named, could face charges of torture.
Reports say she is accused of refusing to let prisoners have water and forcing them to stay in stressful positions.
Denmark supported the US-led invasion of Iraq and has about 500 troops in the country.
The Danish military's statement followed newspaper claims that Danish soldiers had reported their colleague after they disagreed with her interrogation methods.
The Ekstra Bladet newspaper said the woman officer had forced prisoners to sit in "a stressful position for long periods of time".
The officer was ordered to return to Denmark two weeks before her tour of duty was due to end.
The case is the second investigation of alleged prisoner abuse by Danish soldiers in Iraq.
In May a Danish soldier was reprimanded for using his rifle to push a prisoner who had made an obscene gesture.
Incidents of abuse of prisoners by US and UK troops in Iraq were widely reported earlier this year.
