Police have reportedly confiscated a collection of Jay Z's old master recordings that had been stolen.

Producer Chauncey Mahan, who worked with Jay Z from 2008-2009, was allegedly found in possession of Roc-a-Fella Records master recordings from 1998-2002 that Jay Z and his team thought had been lost, according to TMZ.

Mahan told law enforcement that he reached out to Live Nation to tell them that he planned to auction the recordings or hand them over for a $100,000 "storage fee." He continued to say that they had settled on a fee of $75,000.

When Mahan went to the storage facility April 18 where the recordings -- which are valued between $15 million to $20 million -- were being kept, he was reportedly detained by LAPD for questioning, but not arrested. According to Mahan, LAPD were contacted by Jay Z ahead of time.

The LAPD will remain in possession of the recordings until a judge decides who has rightful ownership.

Sources tell TMZ that the Beverly Hills PD is further investigating extortion allegations against Mahan, while Jay Z's team has filed a grand larceny complaint with the NYPD. Jay Z's representatives could not be reached at press time.
