Hip-hop group Beastie Boys are facing a copyright lawsuit just days after the death of bandmember Adam Yauch.

Bosses at music label Tuf America launched a legal battle against the musicians last week, alleging the band illegally sampled Trouble Funk's Say What and Drop The Bomb on four of its early tunes - The New Style, Car Thief, Shadrach and Hold It, Now Hit It.

Tuf America chiefs are seeking a trial to determine the appropriate amount of damages, according to AllHipHop.com.

The papers were filed at the United States District Court for the Southern District of New York on Thursday, just one day before Yauch, also known as MCA, died following a three-year battle with cancer.
