Special police is a question to answer colleagues from a recruiter from the army who was reportedly transported with water to the elite military academy that once was the home of Prinsen William and Harry.
The interrogation is part of a probe to determine whether there is a culture of bullying in Sandhurst.
A probe was launched on the claims that two cadets used the Guantanamo Bay-style interrogation technique.
They would have stabbed their victim before they poured water over a cloth to cause the feeling of drowning.
Now the Sunday People / Mirror can show the alleged incident took place in Sandhurst's old college building – one of the most iconic sites in the center.
One source said: "The investigation is carried out by the Special Investigation Division of the Royal Netherlands Marechaussee
"They spent the first part of last week interviewing cadets from the same company as those involved in the incident.
"They try to determine if this happened earlier and whether it was high jakes or targeted bullying.
" The people involved are accused and the court is tortured if it was bullying. If not, they are still confronted with disciplinary measures and can be expelled. "
The investigation comes because figures show that hundreds of troops do not complain about bullying in the armed forces because they fear that no action will be taken.
One in 10 military personnel claiming to have been victims of" Discrimination, harassment or bullying in a service environment "during the past year.
Figures from the army's Continuing Attitude Survey show that 50 percent of the troops who suffered" bullying, discrimination and / or intimidation "did not complain because they said it would affect their career adversely.
About 63 percent stopped because they believed that nothing would be done, while 30% did not want to go through the complaints process.  Civil servants in Sandhurst hired the Royal Netherlands Marechaussee as soon as the last accusation was reported to them.
The victim claimed that he was subject to the same interrogation technique that has been infamously used by the CIA after the 9/11 attacks.
The three involved cadets, all with leave, have been moved to separate platoons while research is taking place, sources said.
Brigadier Bill Wright, commander of the academy in Camberley, Surrey, said: "I am aware of allegations about an incident at the Royal Military Academy Sandhurst on August 7 with some of our officer Cadets.
" I ordered an investigation from the Royal Netherlands Marechaussee. The army and I expect the highest standards of conduct in Sandhurst.
"Anyone who has failed will be treated forcefully, including dismissal, if applicable."
Only three years ago the then director of the army General Sir Nicholas Carter introduced a new code of conduct to combat bullying.
He told troops in Sandhurst that there was a "no tolerance" approach.
But despite the serious accusations, the commander of the army rejected the allegation and claimed that it was customary.
One user, describing himself as a "war hero," wrote: "Banter-waterboarding is part of an institutional tradition, replacing the firing of fellow recruits."
Another said she was " a couple of high cocks in Sandhurst surprised because of such an indignation ".
One wrote: "Water fuss about nothing: it is unlikely that it caused the victim permanent damage."
