Although he may be incarcerated on Rikers Island, Lil Wayne remains active in his business pursuits. Today, the multi-platinum Rap star and his Young Money Touring, Inc. company sued the Ujaama Talent Agency and its principles: David Nelson and Erskine Isaac.

As recently as this year, Ujaama assisted Wayne and Young Money in scheduling tours. The suit alleges that Nelson and Isaac kept monies due to Wayne and Young Money from last year’s America’s Most Wanted Tour. With Wayne in jail since March, an estimated sum of $375,000 has not been paid.

The rapper’s attorney, Ronald Sweeney, has reportedly made several attempts at collecting the debt on behalf of Wayne and his company, but those have gone unanswered.

Earlier today, it was announced that Drake and other stars are reportedly planning a Welcome Home concert for Wayne, upon his expected November release from Rikers. Wayne is presently serving time on a weapons and drug conviction.
