Dr Murray's lawyer said he had been helping police with inquiries²

Officers from the Drug Enforcement Agency (DEA) entered Dr Conrad Murray's office and removed several items.

Dr Murray's spokeswoman told the BBC the raid（突然袭击，搜捕） was "a surprise to us and it was a surprise to the attorneys".

The doctor, who police say is not a suspect, was at Jackson's mansion³（大厦） and tried to revive（使酒醒） him before he died.

DEA spokeswoman Violet Szeleczky confirmed a search was carried out but said it was not technically⁴ a raid.

Officers "did not raid" the clinic, she told the AFP news agency.

"What this is is the Los Angeles police department have an investigation⁵ and they came to the Drug Enforcement Agency, and they asked us to help them effect a state search warrant here," she added.

Dr Murray's lawyer, Edward Chernoff, confirmed that a search had been carried out.

"The search warrant authorised law enforcement to search for and seize items, including documents, they believed constituted evidence of the offence of manslaughter," he said in a statement posted on his firm's website.

Earlier, Mr Chernoff said his client had been helping police with their inquiries. He has already been interviewed twice by police probing Michael Jackson's death.

Investigators⁶ had asked for medical records in addition to those already provided by Murray.

"The coroner wants to clear up the cause of death; we share that goal," said Mr Chernoff in a statement on his law firm's website on Tuesday.

Painkiller⁷ denial

Speaking a few days after Jackson's death, Mr Chernoff denied Dr Murray administered painkilling⁸ drugs that could have contributed to the singer's death.

Any drugs his client may have given to Jackson were in response to a specific health complaint, the lawyer added.

He said the star still had a faint pulse and was warm when Dr Murray found him in bed.

Mr Chernoff said: "He just happened to find him in his bed, and he wasn't breathing."

Paramedics（护理人员） were called to Jackson's Los Angeles mansion while Dr Murray was performing CPR, according to a recording⁹ of the 911 call.

Mr Chernoff said in Tuesday's statement that Dr Murray had since received unwelcome attention from those angry over the singer's untimely death.

"Dr Murray was the last doctor standing¹⁰ when Michael Jackson died and it seems all the fury is directed toward him," Mr Chernoff said.

He added: "Dr Murray is frustrated¹¹ by negative and often erroneous（错误的，不正确的） media reports - he has to walk around 24/7 with a bodyguard¹².

"He can't operate his practice. He can't go to work because he is harassed¹³（疲倦的，厌烦的） no matter where he goes."
