Prince -- DEA Raids Paisley Park ... Feds Launch Criminal Investigation

Exclusive Details

The DEA is currently at Prince's Paisley Park home, executing a search warrant, and TMZ has learned there is an active federal investigation into doctors who prescribed meds to Prince ... sources connected with the investigation tell TMZ.

Our sources say the feds are conducting the probe under a series of federal laws targeting doctors who sell prescriptions to drug abusers. Our sources say this is precisely the reason for the investigation.

The laws also outlaw doctors and pharmacies who falsify record or forge prescriptions.

Our law enforcement sources tell us ... there's an additional element ... crossing state lines to violate prescription laws.  Our sources say the feds are also looking at the son of the rehab doctor who flew to Minnesota with a backpack full of synthetic opiates. The son, Andrew Kornfeld, was at Prince's home when he died. We're told Andrew is under the federal microscope.
