UPDATE: Dr. Arnold Klein's attorney, Richard L. Charnley, released the following statement this morning:
"The Los Angeles County Coroner's Office has confirmed that Arnold Klein, M.D., is not a subject of the investigation into the death of his treasured friend and patient, Michael Jackson.
"Also, reports in the media claiming that Dr. Klein is allegedly not cooperating in the investigation surrounding Michael Jackson's death are patently false. Dr. Klein has been fully cooperating with and will continue to cooperate with the Los Angeles County Coroner's Office. Dr. Klein has previously produced records to the Coroner's Office in response to a subpoena. Following the Coroner's informal request for additional information, representatives of Dr. Klein agreed to produce further records tomorrow.
"Neither the Coroner's Office nor the Los Angeles Police Department have advised Dr. Klein or his representatives that he is a target of their investigation. Representatives of Dr. Klein will not comment further so as not to jeopardize the integrity of the Coroner's investigation."

City employees paid Michael Jackson's dermatologist a visit late this morning…and it wasn't for crank calls or a checkup.
Los Angeles County Assistant Chief Coroner Ed Winter arrived at Dr. Arnold Klein's Beverly Hills office just before noon today with his badge and a large envelope.
"We are continuing with our investigation," Winter told reporters upon leaving a little more than an hour later. "Dr. Klein is cooperating with it. There's been rumors that Dr. Klein is not cooperating, but that's not true."
Yeah, but when will we actually know something, and what does it have to do with M.J.'s kids' probably-not-biological dad?
"There's a security hold on the case and I can't comment any further," Winter added, though he did say that the findings of the hotly discussed toxicology report are expected to be announced in the middle of next week.
Winter, who also had nothing to say about La Toya Jackson's recent pointed comments, was accompanied by Klein's attorney, Brad Boyer, on his way out of the office.
"There will be no further comments on behalf of Dr. Klein at this time, as we want to allow the coroners to complete their inquest," Boyer said.
Winter also asserted that his visit was in search of medical records, which he recovered. No actual medications were sought or recovered.
"We are not investigating the doctors, we are investigating Mr. Michael Jackson's death," Winter said.
Meanwhile, the DEA's quest for answers regarding Jackson's death have led them to the makers of Diprivan, one of the drugs the star is rumored to have taken.
A representative for Teva Pharmaceutical Industries confirms to E! News that the DEA has contacted them about a lot of Propofol (aka Diprivan) in relation to their investigation.
Denise Bradley, senior director of corporate communications for the company, says that a recall of two separate lots of the drug has also taken place. The lots were reportedly recalled after it was discovered that they contained elevated levels of endotoxins.
"The batch that the DEA contacted us about relating to their investigation is not associated with the lot numbers that are being recalled," she says.
Propofol, a powerful sedative, has been reported as one of the drugs seized from Jackson's Holmby Hills mansion.
E! News is awaiting comment from the CDC, FDA and DEA for further details on the recall of the drug and investigation. Teva Pharmaceutical Industries, an international company headquartered in Israel, recalled the drug voluntarily.
