A Washington, D.C., lawyer says he believes he is the father of basketball star LeBron James, and he has filed suit in federal court alleging a scheme to cover up paternity.

In a complaint filed June 23, Leicester Bryce Stovell says he has been trying to determine paternity since 2007, at one point taking a DNA test in Cleveland. He alleges that the test results were falsified and that James; his mother, Gloria James; and his attorney have prevented further attempts to settle the issue. The complaint was first reported Wednesday on the website TMZ.
