Police in Georgia have raided the office of Canadian professional wrestler Chris Benoit's personal physician, authorities said Thursday.
Federal drug agents and sheriff's deputies began carrying out the raid Wednesday night and concluded early Thursday, reports the Associated Press.
Officials said they were searching for records and other items in Dr. Phil Astin's office in Carrollton, near Atlanta.
No arrests were made in the raid.
Chuvalo Truesdell, a spokesperson for the Drug Enforcement Administration (DEA) in Atlanta, told AP the search warrant was obtained in connection with the investigation into the weekend deaths of Benoit, his wife and young son.
Truesdell wasn't specific about the records police were looking for, nor did he say what items were seized.
Astin was a longtime friend of Benoit and said earlier this week he had been treating the Montreal-born wrestler for low testosterone levels. The condition likely originated from previous steroid use, said the doctor.
Astin would not say what, if any, medications he prescribed when Benoit visited his office last Friday -- just hours before the wrestler killed his wife and son and then hanged himself at their home in Fayetteville.
Astin said Benoit showed no signs of distress or rage during the Friday visit.
Anabolic steroids were found in Benoit's home, leading officials to speculate on whether the drugs played a role in the slayings. Some experts believe steroids cause paranoia, depression and violent outbursts known as "roid rage."
World Wrestling Entertainment (WWE) dismissed the steroid theory after the deaths were announced, saying Benoit tested negative for the drug the last time he was tested on April 10.
On Thursday, WWE owner Vince McMahon urged the public not to assume steroids were behind the murder-suicide.
"It's all speculation until the toxicology reports come back," McMahon said on NBC's "Today" show.
Authorities in Georgia, meanwhile, were investigating a link between Benoit and Signature Pharmacy and MedXLife.com -- a Florida business that sold steroids on the Internet.
AP reports that prosecutors in upstate New York, who have been investigating the company's drug sales, said Benoit bought the company's products.
The lawyer for MedXLife co-owner Dr. Gary Brandwein denied allegations that his client's company sold steroids to Benoit. Brandwein was accused of signing and sending prescriptions without ever seeing patients. He pleaded not guilty to six counts related to the criminal sale of a controlled substance.
Six people have pleaded guilty in the investigation, and 20 more have been arrested, including doctors and pharmacists.
Jerry McDevitt, a lawyer for the WWE, said the drugs found in Benoit's house were legitimately prescribed.
"There's no question, none of these drugs are out there, none of these drugs came from Internet pharmacies," he said.
Also on Thursday, the father of Chris Benoit said a private memorial service will be held in Canada, but he did not give a date for the service and no further details were available.
