The US Attorney's office and Drug Enforcement Administration are joining legendary singer Prince's death investigation.
The "Purple Rain" hitmaker was found dead at his home last month. He was 57.
"The U.S. Attorney's Office and DEA are joining the Carver County Sheriff's investigation," a spokesperson for the US Attorney's office told E! Online.
"The DEA and U.S. Attorney's Office are able to augment this local investigation with federal resources and expertise about prescription drug diversion. While this remains an ongoing investigation, we will have no further comment."
The Carver County Sheriff's Department said, "The US Attorney and DEA have agreed to provide resources and expertise in our investigation."
The new involvement in the investigation come shortly after learning that the musician died one day before meeting with a California doctor who specialises in addiction, according to a new report from the Minneapolis Star Tribune.
The singer was allegedly suffering from an addiction to pain killers and had representatives reach out to Dr Howard Kornfeld, a national authority on opioid addiction treatment, because Prince was "dealing with a grave medical emergency," said William Mauzy, an attorney working with the Kornfeld family.
Authorities ruled out foul play and suicide.
