MADRID (AP) - Spain's anti-doping agency says state prosecutors could seek retroactive punishment against those who may have broken national laws during their alleged involvement in the Lance Armstrong doping scandal.

The AEA says it handed the U.S. Anti-Doping Agency dossier over to prosecutors to investigate whether charges should be invoked for crimes committed in Spain.

Spanish doctors Luis Garcia del Moral and Pedro Celaya and Pepe Marti are alleged to have been key figures in what USADA calls "the most sophisticated doping program that sport has ever seen." It allegedly helped Armstrong win seven Tour de France titles from 1999-2005 for U.S. Postal Service and Discovery Channel. Former team principal Johan Bruyneel was a Spanish resident at the time.

USADA banned Armstrong for life and says he should be stripped of his seven Tour titles.
