HOUSTON (AP)-Southern University Athletic Director Greg LaFleur is free on bond after his arrest in Houston on a charge of soliciting a prostitute. Police records show the 52-year-old former NFL tight end was arrested on a downtown Houston street about 8:30 p.m. Sunday and released Monday after posting $500 bond. Court records showed no attorney for LeFleur, whose home telephone has been disconnected. University spokesman Edward Pratt says Southern officials will investigate, then "will determine what action or actions are necessary." He declined further comment. LaFleur has been Southern's athletic director for six years. The Ville Platte, La., native and former LSU star tight end and receiver played with the Philadelphia Eagles, St. Louis Cardinals and Indianapolis Colts in the NFL.
