MADRID -- A judge has ordered an investigation into Spain's Civil Guard for irregularities in its management of a doping case involving world steeplechase champion Marta Dominguez.
Judge Mercedes Perez ruled Friday that police did not follow correct procedures in Operation Galgo, which led to Dominguez being among 14 people detained in December. She was cleared of doping and trafficking charges in July.
The Madrid court says the Civil Guard did not follow the proper "chain of command" in delivering certain samples to a Cologne laboratory.
Perez also says other evidence was missing, and samples taken from former European 5,000-meter champion Alberto Garcia's residence and intercepted from the house of Dominguez's trainer were invalid.
