LOS ANGELES -- CONCACAF is suing a California company for at least $50 million in an alleged kickback scheme involving two former executives of the soccer body.

The Confederation of North, Central America and the Caribbean Association Football filed a lawsuit in federal court in Los Angeles on Monday. The lawsuit names Los Angeles area-based Cartan Tours, its owner, an executive and three related companies.

Messages left for an attorney and an executive at Cartan Tours were not immediately returned Wednesday.

The lawsuit alleges ''a clandestine, kickback-based and parasitic relationship'' between Cartan and two former CONCACAF executives, president Jeffrey Webb and general secretary Enrique Sanz. Webb and Sanz were not being sued.

Webb has pleaded guilty to federal corruption charges after his arrest with other FIFA officials in Switzerland in May. Webb also was a FIFA vice president and executive committee member.
