WASHINGTON, May 10 (UPI) -- A CIA report has criticized the use of sleep deprivation to interrogate diapered and shackled prisoners, U.S. Justice Department memos said.
Memos released last month by the Obama administration said more than 25 CIA prisoners were subjected to sleep deprivation, some kept awake for as long as 11 days, the Los Angeles Times reported Sunday.
An internal CIA report issued in 2004 was critical of the agency's use of sleep deprivation because of how the technique was applied, the Times reported.
Prisoners, clad only in diapers, had their feet shackled to the floor and hands cuffed close to their chins, Justice Department memos said. Prisoners who started to fall asleep would tilt over and be caught by their chains.
Sleep deprivation was prohibited by President Barack Obama's ban in January on harsh interrogation methods.
A task force is reviewing its use along with other methods the CIA might use in future interrogations, the Times said.
