LOS ANGELES, California (CNN) -- The Los Angeles Coroner's chief investigator revisited the office of Michael Jackson's dermatologist Wednesday, even though the coroner announced last week his "thorough and comprehensive" report was completed. 

Dr. Arnold Klein denied in a CNN interview last month that he had given Jackson dangerous drugs. 

"We wanted some additional information, and they provided it," Ed Winter said as he emerged 90 minutes after entering Dr. Arnold Klein's Beverly Hills, California, dermatology clinic. 

Winter, who also visited Klein's office on July 14, said the doctor's staff and lawyers cooperated with his requests. 

Garo Ghazarian, one of Klein's two lawyers on the scene, said the doctor did not meet with Winter. 

"They had inquiries born out of information they wanted to corroborate," Ghazarian said. 

Ghazarian said he was added to Klein's legal team "to take a look and see if there's any cause for concern in light of media reports" that investigators were considering criminal charges against him. 

"I have seen no cause for concern on behalf of my client, Dr. Arnold Klein," Ghazarian said. 

The coroner's office said more than a week ago that a "thorough and comprehensive" report into the death of Michael Jackson is complete, but police have requested that the report not be released yet because of the ongoing criminal investigation. 

The coroner's office said it would abide by the request that "the cause and manner of death remain confidential," and referred all questions to the Los Angeles Police Department. 

Winter would not say what prompted the coroner's office to revisit its conclusions.
