Texas financier R. Allen Stanford, who faces federal criminal charges related to an alleged conspiracy to defraud investors, “has been returned to a lockup after being hospitalized for treatment of a concussion following a jail fight,” according to www.nbcdfw.com, an NBC Dallas affiliate’s Web site.

Stanford’s court-appointed attorney Kent Schaffer, a partner in Houston’s Bires & Schaffer, told The Associated Press on Monday that his client was injured in a fight on Thursday with another inmate at the Joe Corley Detention Facility in Conroe, Texas, near Houston. Schaffer did not immediately respond to a call seeking comment.
