SAN DIEGO » A San Diego college student who was locked and handcuffed in a U.S. Drug Enforcement Administration cell for five days without food or water says he exchanged words with a man through his cell door just before a light was turned off.

Daniel Chong told reporters Thursday that he doesn’t remember what was said. But Chong does say he spent at least two days in darkness, at times banging on the cell door.

Nobody responded.

The U.S. Justice Department inspector general says four DEA employees saw or heard Chong during his April 2012 incarceration.

A summary of the investigation, released Tuesday, doesn’t indicate when the employees encountered Chong or what they heard or saw.

Chong and his attorneys are calling for the release of the full report.
