CHANHASSEN, Minn. -- Agents from the U.S. Drug Enforcement Administration and local sheriff's deputies were at the Minnesota home of Prince on Tuesday as part of an ongoing investigation into the music legend's death, a law enforcement official told CNN.

The DEA agents were executing a federal search warrant, the source said.

CNN affiliate WCCO reported more than a dozen vehicles were at the house where Prince, 57, died April 21.

"Detectives are revisiting the scene at Paisley Park as a component of a complete investigation. No other information is available," the Carver County Sheriff's Office tweeted.

The U.S. Attorney's Office and the DEA announced last week they were joining forces with local investigators, led by the sheriff's office in Carver County, to investigate Prince's death.

The county includes the Minneapolis suburb of Chanhassen, where Prince's Paisley Park complex is located.

Officials have yet to publicly comment on what killed Prince. Results of an April 22 autopsy are pending.

According to a law enforcement source, investigators found prescription opioid medication on Prince and at Paisley Park after his death. Federal investigators will try to determine if people in Prince's inner circle may have helped obtain drugs for him, law enforcement officials familiar with the investigation told CNN last week.

Opioids reduce pain by switching off pain receptors in the brain.

They are among the most widely prescribed drugs in the United States, the Centers for Disease Control and Prevention says. Prescription opioids include painkillers such as morphine, oxycodone and hydrocodone, according to the CDC.

Opioids produce an increased pain tolerance and a sense of euphoria. They trigger a craving when the drug is absent.
