The rapper - currently incarcerated at New York`s Riker`s Island prison on weapons charges - faces a fresh legal battle after his expected release on November 4, as a producer has launched a copyright infringement lawsuit against him.
Michael `Mali Boi` Bradford is claiming for unpaid royalties he believes he is due for creating the beat to Wayne`s single `Mrs. Officer`.
He says he came up with the rhythm five years before it was reworked by Deezle, who is credited as the producer of the track.
Deezle is also reportedly launching legal action, saying he has not been paid royalties for the 2008 single, from Wayne`s breakthrough `Tha Carter III` album.
Wayne was sentenced to a year in prison in March and this week it was revealed he has been put into solitary confinement after he was caught with a banned MP3 player and headphones in his cell.
Later a message was posted on Wayne`s twitter page, on his behalf, which read: "I can no longer write my fans, as difficult as this maybe to say please stop sending me mail, I luv u and will see you soon. (sic)"
Wayne`s latest album, `I Am Not A Human Being` - recorded before he went to jail - is expected to reach number one in the US charts this weekend.
