BUFFALO, N.Y. (AP) - The latest lawyer to represent a New York man in what authorities now say is a fraudulent lawsuit against Facebook wants off the case.

Ohio attorney Dean Boland moved Tuesday in federal court in Buffalo to withdraw as Paul Celglia's lawyer. Boland's motion doesn't say why he wants off the case, but it says it has nothing to do with any belief that Ceglia engaged in fraud.

Boland is among more than a half dozen lawyers and law firms who've signed on to represent Ceglia and then pulled out. Ceglia's 2010 lawsuit claims half-ownership of Menlo Park, Calif.-based Facebook based on a 2003 contract with founder Mark Zuckerberg.

Ceglia was arrested at his Wellsville, N.Y., home last week. Authorities say he doctored, fabricated and destroyed evidence to support the lawsuit.
